First Look: Gossamer Gear 2014 Murmur Hyperlight Backpack

By Will Rietveld

Introduction and History

The Murmur is a frameless minimalist rucksack for ultralight backpacking. The 2014 version is generation 3 of this popular pack. The dimensions and volume remain unchanged: 2200 cubic inches (36 liters). The pack is available in only one size.

The original silnylon Murmur Gen 1 came out in 2008, weighed 7.5 ounces, and had wide, thick shoulder straps padded with lightweight foam or your spare hiking socks. It even had a pair of side compression straps.

The 2012 Gen 2 Murmur is made of 140 denier Dyneema Gridstop and silnylon, has an Over the Top flap (no pocket), and thinner shoulder straps. The pack gained 1.5 ounces, but added useful features and durability.

Now the Gen 3 2014 Murmur is being introduced. This version is constructed of lightweight and durable Cordura high-tenacity nylon 6-6 ripstop nylon and Robic high-tenacity nylon, has thin perforated foam shoulder straps, replaces the Over the Top flap with a drybag closure, and adds hipbelt wings with pockets. The weight by my scale is 10.85 ounces without the provided SitLight pad and shock cord system. So, the latest Murmur has gained another 1.85 ounces; what are the changes and how much has the pack been improved?

The new 2014 Murmur backpack is unchanged in dimensions and volume and is available in one size. The weight has increased 3.3 ounces from the original.

Description

The fabric used for the body of the new Murmur is 20-denier Cordura high-tenacity 6-6 ripstop nylon, the bottom is 100-denier Robic 100% high-tenacity nylon. These fabrics are lighter and more durable than the previous 140 denier Dyneema Gridstop fabric. Why? -- Because Dyneema Gridstop fabric is ordinary nylon 6 with a grid of high-strength Spectra fibers for strength. High-tenacity 6-6 nylon is industrial strength and highly abrasion-resistant.  If you are interested in learning more about these fabrics, Google “6-6 nylon” and “Robic fabrics” to get the details. There is a big difference between ordinary nylon 6 and high-tenacity nylon 6-6 and Robic.

The following photo sequence shows important details of the new Murmur.

The frontpanel has the same pocket design as previous versions. The big front pocket is a new more durable Darlington Mesh; fabric panels with lashing loops are attached to the mesh. Trekking pole holders have been added on the bottom left and removable tool loops on the upper body.

The backpanel has a thin Power Mesh for the pad sleeve. Note that it absorbs water (and sweat) as shown. A SitLight pad is included with the pack, which can be removed and used as a sit pad on breaks.

Side view: the side pockets are fabric and stretch mesh (same mesh as the front pocket), and are fairly tall. With the pack on, a water bottle can be inched out and replaced in the side pockets, but I would not rate it as easy. Note that there are no loops sewn in the side seams to attach a shock cord or compression system.

 

The top has a new drybag-type closure that replaces the Over the Top flap on the previous version. One side has a stiffener to facilitate rolling the top down. It’s held down with two side straps (see previous photo); their ¾-inch width is a bit on the heavy side for an ultralight backpack.

The bottom of the pack, including the bottom of the side pockets, is a 100% high tenacity Robic nylon fabric, which is very abrasion resistant. The hipbelt wings are attached with clips, so they are removable. There are two attachment loops, so the pack torso length can be shortened if desired.

Close-up view of the front and side mesh pockets.

The hipbelt wings each have a zippered mesh pocket. Note the clips that attach the hipbelt to the pack, and the second loop 2 inches higher to shorten the pack torso length.

Trekking poles attached to the pack’s trekking pole holders.

A folded ThinLight pad (about 3 ounces) in the pad sleeve adds a bit more weight than the provided SitLight pad (1.75 ounces), but it’s more versatile.

The new pack’s shoulder straps (and hipbelt wings) are padded with a thin perforated Wall Mesh, which should be very breathable.

 

Initial Testing and First Impressions

I carried the new Murmur packed with weights of 10, 15, and 20 pounds on seven day hikes, one of which was an ascent of a 13,000’ peak. The other hikes were my daily 5 mile walk up a local mountain. Following are my initial impressions.

The new Murmur comfortably carries loads up to 15 pounds; it’s less comfortable at its limit of 20 pounds. This agrees with Gossamer Gear’s specifications. The reason for its reduced comfort with heavier loads is pack torso collapse, which puts more weight on the shoulders, and the thin shoulder straps distort and do not spread the weight.

This photo shows the exact same load in the original silnylon Murmur. The shoulder straps are wider, thicker, and more supportive. As with any frameless backpack, pack torso collapse still occurs, putting more weight on the shoulders, but the wider, thicker shoulder straps in this case spread the weight over the shoulders, substantially increasing comfort.

The new Murmur’s hipbelt wings, padded with the same Wall Mesh, are no better than the shoulder straps; they collapse with heaver loads and do not spread the weight. I found that the ordinary webbing waist strap on the original Murmur is just as comfortable.

• The new Murmur effectively uses the latest high-tenacity nylon fabrics and mesh to enhance durability while minimizing weight.
• Small webbing loops in the side seams have been eliminated, so the pack does not have any volume compression capability. On previous versions I was able to run thin cords with cordlocks through those loops to create a compression system.
• I really like the new drybag-style top closure; it’s easy to use, keeps water from entering the pack, and tightly secures the top.
• The trekking pole holders are a nice feature and add little weight. There are many times on a backpacking trip where I want to stow my poles and have my hands free.
• The Murmur is available in only one size. I measured the pack torso length at 18.5 inches (center of hipbelt to shoulder strap attachment), which translates to a size Medium. Connecting the hipbelt wings to the upper loops results in a pack torso length of about 16.5 inches for shorter hikers. I found the pack to be a bit too short for taller hikers like me, but usable with lighter loads.
• Overall, I like all of the changes in materials and design of the new 2014 Murmur, except the very thin padding in the shoulder straps and hipbelt wings. When I compared the new pack with the original Murmur’s thicker/wider shoulder straps, I found the original pack substantially more comfortable carrying the same 20-pound load. Also, the new version does not have any volume adjustment capability as previous versions did.

 Questions for Readers

I have been pondering the following questions, and hope that you can enlighten me. Your responses will help me keep up on current trends.

1. Does anyone use the virtual frame technique anymore? That requires a closed cell foam pad. With the availability of LW comfortable inflatable sleeping pads, it seems like most hikers are adopting them, which makes it difficult to create a virtual frame. How do you create pack rigidity, or not?
2. When you use an UL frameless backpack, like the Murmur, what is your initial weight? How comfortable is that weight in a frameless backpack, or do you go to a different pack for those weights?

After further testing of the new Murmur on backpacking trips I will add additional comments to this article and convert it to a review, stay tuned.

GEAR REVIEW: Six Moon Designs Flight 40-FKT Backpack

By Will Rietveld

Update

When I started this review in 2014 the Flight 40 was offered with two harness options -- traditional shoulder straps or a vest harness. I opted for the vest harness. Since then, to simplify things, SMD has split the original Flight 40 into two separate models. The Flight 40 Backpacker and the Flight 40 FKT. The difference between the two models is that the Flight 40 FKT (tested here) utilizes the Vest Yoke, While the Flight 40 Backpacker uses a more traditional standard Shoulder Yoke. The two packs now have a bungie attachment system on the front instead of the daisy chain on my test pack.

The main updates in the 2015 Flight 40-FKT are as follows:

•  Adjustable and removable harness. You can choose either the Vest or Standard Shoulder Straps.
•  Seven different harness options available (4 vest harneses and 3 standard harneses), along with 8 different hip belts. This gives the Flight 40  63 different possible configurations.
•  SMD now uses  a single bag, vs the dual sizes of before. The volume of the pack is now 44L (vs. 48L before) for the M/L version. The volume listed does not include any of the pocket storage.
•  Side pockets are now much deeper and have a closure at the top.
•  A removable hydration is now included.
•  Features like hip belt pockets, etc. are included in the standard price.
•  Several new color options are available.

Following is my review of the pre-2015 model:

Six Moon Designs has reinvented and consolidated their backpack line down to two models – the Fusion and the Flight – each in two size capacities.

The Fusion 50 and 65, with a sturdy frame, adjustable torso, and capable suspension are sub 2.5-pound backpacks designed to satisfy the needs of most lightweight backpackers.

The lighter weight Flight 30 and 40 backpacks have a Delrin peripheral loop frame that is anchored to a weight-dispersing hipbelt, and features a unique vest harness. These packs offer extra comfort for backpackers at the lower end of lightweight or the higher end of ultralight.

The vest harness is what triggered my interest in the Flight. Earlier this year I tested the Ultimate Directions Fastpack 20, which also has a vest harness, and was impressed with its carry comfort and freedom of movement from not having a hipbelt. It felt like I was wearing the pack. But a hipbelt-free pack is only comfortable up to a certain point, about 10 pounds.

Nevertheless a vest harness is a refreshingly innovative feature for a backpack, and intrigued me enough to test a backpack with that feature. As you will see the Flight has numerous complementary features that add up to a very comfortable and capable backpack.

The new Six Moon Designs Fusion 40 backpack actually has 48 liters (2900 cubic inches) of volume (which includes the extension collar and pockets) in size M/L, and weighs 32 ounces (2 pounds). The smaller volume Flight 30 (not shown) has 36 liters (2200 cubic inches) of volume in size M/L and weighs 21 ounces.

 

Description

The following photo series shows the Flight’s notable features and details.

The Backpanel View shows the business side of the Flight. The center is well padded against the backbone. The shoulder straps flare out at the bottom to create the vest harness with two sternum straps. It has a two-point attachment to the pack body. The vest harness has six pockets, two of them zippered. The pack has a total of 10 exterior pockets.

Close up of the vest harness, with red bandanas inserted in the three pockets on each wing. It connects with two sternum straps.

Inside the pack, a peripheral Delrin rod is anchored to a high density polyethylene (HDPE) reinforcement attached to the back of the hipbelt. There is one zippered mesh security pocket on the inside. The pack does not have a sleeve for a hydration reservoir, but there are two loops for hanging one.

The wide padded hipbelt has a thin sheet of HDPE under the outer skin to provide stiffness and distribute weight. It’s tightened with a four-pull system connected to one central buckle. The HDPE layer in the hipbelt has a 6-inch cutout at each end, which allows the hipbelt to wrap and tighten around the hipbone. The hipbelt pockets have a large capacity, a big plus.

The pack’s frontpanel has two large stretch nylon pockets that wrap around the sides, and a combination daisy chain, lower ice axe loop, and upper top compression strap down the middle.

Each side of the pack has a four-point compression system that tightens with one pull. Note that a Platypus hydration system fits nicely in a side pocket.

The top has a 10.5-inch extension collar with a drybag-type closure and top compression strap.

The bottom of the pack, and other abrasion areas, are 410 denier pack cloth. The pack body is 210 denier Robic fabric. Note that the main shoulder strap attachment is to a wing on the bottom of the pack; the other attachment is to a wing located at the top of the side pockets.

 

Preliminary Testing

I tested the Flight 40 for this First Look article by carrying it on day hikes with 20, 25, and 30 pounds of weight. I loaded the pack with an old sleeping bag to fill it out, and placed 2-liter bottles of water high against the backpanel to simulate a backpacking load. Each hike was about 5 miles and took 2 hours.

My initial impressions of the Flight 40 are as follows:

• Note that the actual volume of size M/L is 48 liters, not 40 liters.
• In spite of its lightweight peripheral rod frame (see photo 4), the Flight is a capable load hauler. It easily and comfortably carried everything I put in it, up to 30 pounds. It gave me the impression that it is capable of carrying even more weight, if I am. For a 48 liter pack, the most a hiker is likely to carry is 25 to 30 pounds.
• Its load carrying ability comes from the peripheral rod frame that is solidly anchored to the back of the hipbelt in the lumbar area, in combination with a stiffened hipbelt that spreads the weight, plus a bifurcated hipbelt that wraps around the hipbones. The pack effectively transferred all the weight to my hips and the hipbelt stayed on my hips, which is remarkable for a 2-pound backpack.
• I really like the vest harness, it makes the pack feel like it’s being worn rather than carried.
• I also like the six stow pockets on the vest harness. They are made of stretch nylon and are handy for a digital camera, snacks, or anything used often on the trail. Two of the pockets are zipped.
• Further, I also really like the large hipbelt pockets, which are the largest attached pockets I know of.
• Some hikers will miss a hydration sleeve; the Flight doesn’t have one. That doesn’t bother me since I use a 1-liter Platypus flask based hydration system in a side pocket, which is lightweight and convenient. The side pockets on the Flight are perfect for that arrangement.
• One thing I miss on the Flight is a large stretch mesh pocket on the front of the pack. That’s where I put a large turkey roaster bag containing all of the items I want to keep handy on the trail. Fortunately, that bag of stuff fits into the other side pocket. Overall, however, there seems to be less pocket volume on the front of the Flight, compared to a conventional design with one large front pocket plus two side pockets.
• The middle strip on the front of the pack measures 4.5 inches wide and has a daisy chain plus 8 attachment loops, enabling the Flight to easily carry items lashed to the front of the pack. For extra capacity, one could attach a tall, narrow gear bag to the front.
• It is not easy to reach and replace a water bottle carried in a side pocket. The pockets are deep, large, and contain a compression strap within. One is likely to have other items stuffed in the pocket, plus the compression strap interferes, so inserting a bottle back in the pocket (with the pack on) is the challenge.
• The Flight is built of bomber fabrics. They are very durable and will last a long time, but from a lightweight point of view, they are overkill. The counter argument is that heavier fabric doesn’t contribute much extra weight to a backpack, perhaps 3 to 4 ounces in this case; most of a pack’s weight comes from the frame, reinforced hipbelt, straps, and connectors. 

 

Field Testing

I carried the Flight 40 on several multi-day backpacks loaded with 21-23 pounds of lightweight gear.

  Although the Flight 40 would seem to be too small in volume for lightweight backpacking, its actual volume (in size M/L) is 48 liters, and it in fact has plenty of volume for a multi-day trip using a true lightweight gear kit. That assumes good gear choices and no unnecessary extras.

This pack's load carrying capacity is indeed remarkable, considering the pack's minimal lightweight frame and overall light weight. It carried the stated loads comfortably all day. That capability is due to a combination of a lightweight Delrin rod loop frame that is anchored to a supportive hipbelt with a four strap tightening system and cutout that molds the hipbelt to your hip bones. This pack is capable of transferring most (if not all) of the pack weight onto your hips.

I tested the pack with the vest harness option (now the FKT model). The vest harness with two sternum straps helps to distribute weight so overall it feels like you are wearing the pack rather than carrying it. The vest also adds lots of pockets to keep things handy. And the hipbelt pockets are the largest I have seen and also hold a lot of stuff.

This is a pack you will want to use with a hydration system because a water bottle in a side pocket is not easily reachable with the pack on, and part of the side compression system is inside the pocket so it is hard to insert a water bottle with the pack on. There is no hydration sleeve inside the pack, so a hydration reservoir would either need to go inside at the top of the load (there are two hose ports) or in a side pocket. My preference is the latter, for easier access and easy monitoring of how much water I have left.

The side stretch mesh pockets are large and hold a lot, but if you use one for carrying water, only limited outside pocket space if left for gear. I personally missed having a large stretch pocket on the front of the pack, along with two side pockets. I like to put all of my smaller items in a large turkey roaster bag (or other dry bag) and stuff that in a large stretch pocket on the front of the pack, but the Flight 40 didn't give me that option. I was able to stuff a smaller version in a side pocket (with a hydration reservoir in the other), but it was less then ideal. The daisy chain in the middle (now a bungie attachment system) allows one to strap a gear bag (or other gear item) onto the front of the pack, which would work okay.

Assessment

Overall the Flight 40 is a very capable load hauler for its light weight, and I consider its volume to be ample for a multi-day backpack with lightweight gear. Many backpackers fear getting a pack that turns out to be too small in volume, but frankly you are better off to know the volume of your gear kit and match the size of your pack to the size of your load. A right-sized pack that is completely filled carries much better than a oversized pack partially filled. It you must purchase a larger pack "just to be sure its big enough", get one with a good compression system so you can adjust pack volume to get a tight pack no matter the load size. For that approach the Flight 40 is a good choice; it has an excellent side and top compression system.

My main issue with the Flight 40 is the outside pocket design. Granted, a pack designer needs to choose a single design that will please a majority of buyers, and then buyers need to decide if it meets their needs and preferences. I personally prefer a three pocket design that covers the sides and front of the pack with pockets. Other people like a "cleaner look". You need to make your own decision.

Other than the pocket design, I like everything about the Flight 40. Its an amazingly capable and comfortable backpack on target for a true lightweight backpacker.

A Technique for Using a Steripen with a Hydration System

By Will Rietveld

My (current) favorite lightweight water purification system is the rechargeable Steripen Freedom, a 2.65 ounce (without carry case) device that purifies water with UV light. Why? – Because there is no wait time or sucking through a filter, just treat and drink.

I prefer to use a lightweight hydration system carried in a side pocket, but the flask has a narrow opening, which is not amenable to using a Steripen. The Steripen requires an open container or wide mouth bottle to wave the device around in the water.

So how do you use it with a hydration system, in ultralight style, which means minimal extra weight?

My ultralight backpacking friend Tom Galbraith came up with a clever and simple solution, described below. Here’s a photo of Tom on a recent backpacking trip two weeks after he bicycled 1700 miles on the Continental Divide road route. Credit for the idea goes to Tom, and I show the method here with his permission.

The technique is to use a gallon size zip-lock bag to scoop up water, treat the water in the bag with the Steripen, then transfer the water into your hydration reservoir. We like to use a Platypus flask.

Equipment needed is a Steripen, 1-gallon zip-lock plastic bag with slider closure, and a flask.

Scoop up water into the plastic bag. It’s easy to do while holding the bag open with two hands. I often treat 2 to 3 liters at a time and share the treated water with my hiking companions. For mountain hiking, I usually carry 1 liter or less to minimize weight.

 

Treat the water with the Steripen, which uses UV-C light to sterilize organisms. The Steripen Freedom uses a 48 second cycle to treat 1 pint of water, so multiple cycles are required, depending on the quantity of water. Simply dunk the Steripen into the water (it turns on automatically) and wave it around in the bag.

Transfer the treated water into the flask. If you are doing it alone, it helps to open the slider on the zip-lock about 1.5 inches, lay the zip-lock bag over your leg to support it, and pour into your flask held with the other hand.

This technique is a head-slapper in its simplicity and adds only a fraction of an ounce to your pack, besides the Steripen.

I have tried just about every water treatment and hydration system available, and this system is my current favorite. Its not the lightest -- Aqua-Mira drops or tablets are lighter -- but I like the convenience of fast treatment with the Steripen and being able to drink on the fly with the hydration system. In the mountains, where water is abundant, I treat and carry a liter of water at a time, which is a good balance of light weight and convenience.

Outdoor Retailer Summer Market 2014 – Gear of Interest for Lightweight and Ultralight Backcountry Travel – Sleeping Pads, Shelters, Backpacks, and Trekking Poles. Plus the Lightest Rain Jacket on the Market, Made Lighter.

By Will Rietveld and Janet Reichl

We publish our main OR coverage on the Gossamer Gear blog. That coverage omits sleeping pads, shelters, backpacks, and trekking poles due to a potential conflict of interest because Gossamer Gear sells gear in those categories. We publish our coverage in those categories here on our own independent blog.

Note: items featured in this collection of gear will be available in spring 2015 unless stated otherwise.

Sleeping Pads

There were a bunch of new pads this time, including one that is full length and weighs just 6.5 ounces and costs $25 – I’ll bet that gets your interest! For lightweight and minimalist pads, we definitely have more options.

Adventure Medical Kits Escape Sleeping Pad. Made of aluminized plastic with 85% heat reflectivity, this full size pad weighs just 6.5 ounces and will cost around $25-$30. That’s the good news. The downside is this is considered an emergency pad, which means it’s not designed for continuous use. Obviously the plastic is pretty thin for it to be that light weight. Ultralight backpackers will see it a little differently: how long will it last if I use it carefully, like on top of a good groundsheet or a Gossamer Gear ThinLight pad? I look forward to testing that idea. The Escape Pad can be paired with AMKs 5.5 ounce Escape Bivy (that we reported on last summer) to create a 12-ounce sleeping system.

Exped SynMat Hyperlite Sleeping Pad. This new R-3.2 insulated, full-length, 11.6-ounce sleeping pad is claimed to be the lightest insulated sleeping pad when it comes out in spring 2015. It will actually be available in three sizes: the 71x20.5x2.75 inch version (the lightest one) will cost $169; the wide version will cost $179, and a long-wide version will cost $189. Exped laminates the insulation to both the top and bottom surfaces within the pad to get maximal benefit from the enclosed synthetic insulation. Also, their pads use an exclusive pair of inflation and deflation valves (the intake one is one-way) instead of the familiar plastic twist valve, which they claim is prone to breakage and leakage.

Big Agnes Green Ridge Pad. This new pad will replace the Clearview, and yes it’s green rather than clear. It will be available in a range of sizes like the Clearview; the lightest one is 20x60x2.5 inches and 13 ounces; $60. It does gain a bit of weight since the Clearview in that size was about 11.5 ounces as I recall. This is a good value for a lightweight inflatable non-insulated sleeping pad.

Big Agnes Double Z Sleeping Pad. For anyone who wants a lightweight thick sleeping pad, the 4-inch thick Double Z pad weighs only 17 ounces and costs $80, also a good value. 17 ounces is heavy for ultralight backpackers, but lightweight backpackers may find this pad made in heaven. After all, a standard Therm-a-Rest foam pad weighs about a pound and a half, so this is lighter and much more comfortable than a conventional pad. You might faint while blowing it up at high elevations, but that’s another matter.

Sea To Summit Sleeping Pads. Sea To Summit introduced a line of sleeping bags a couple of years ago, and now they will be getting into the sleeping pad business with a new line of pads that includes three versions: Comfort Plus, Comfort Light, and Ultralight. I will focus on the latter version because it’s the lightest one at 11.5 ounces for the Small size (66x21.5x2 inches), 12.5 ounces for the Regular size (72x21.5x2 inches), and 16 ounces for the Large size (78x25x2 inches); MSRPs are $100 for Small and Regular and $129 for Large. These pads feature Air-Sprung Cells which means the cells are independent; pressing on one cell does not affect adjacent cells. Other features are liquid extrusion TPU lamination which prevents fabric delamination, anti-microbial treatment of the interior to prevent mold development, and a multi-function valve that allows for easy inflation, rapid deflation, and a fine-tuned pressure adjustment. The bottom is 40 denier nylon for durability, and the R-value is 0.7. A ThermoLite insulated version will also be available for $30 more and adds 3 ounces.

Crazy Creek Air Chair Pad. The good news is this minimalist 36x17.5 inch pad weighs just 7.4 ounces; the bad news is you need to buy the Air Chair to get the pad, $79.75. The pad is made by Klymit, so perhaps if we encourage them enough, one company or the other will offer the pad separately. At one time Kooka Bay offered a torso pad with similar dimensions that weighed only 5.3 ounces, but alas Kooka Bay is gone. Hopefully, someone will fill the void.

 

Shelters

Last summer we reported that we are starting to see two-person double wall shelters in the 2.5 pound range. A year later we are seeing more of them, and even some weighing just 2 pounds, which is remarkable. With the availability of high-tenacity nylon fabrics and coatings that make the fabric stronger, not weaker, manufacturers are less reluctant to use thinner fabrics in shelters. However, these fabrics are more expensive to manufacture, so expect to pay more. Tents made of 10 to 20 denier fabrics are wonderfully lightweight but require reasonable care to maintain their functionality and extend their longevity.

Also, it seems that manufacturers have gone beyond the stage where they were shrinking and de-featuring tents to lighten them. Buyers were simply not very interested in a two-person tent with only one door and little headroom. Now, with the use of lighter weight fabrics and lighter poles or the use of trekking poles, we are seeing more and more tents in the 2 to 2.5 pound range (trail weight) with two vestibuled doors and ample floor space and headroom, which is what buyers want.

Exped Mira Hyperlite (1, 2, and 3-person versions, double wall, semi-freestanding). This is a good one to start off with. This tent is supported by three poles in sleeves, which is a plus for distributing wind force thereby increasing stability.  It has dead-end pole sleeves for assembly convenience. The one person version has one side entry with vestibule, while the 2- and 3-person versions have two doors with vestibules. Floor dimensions for the 2P version are 49x85, with 43 inches of headroom. The Mira tents are made of 20 denier fabric with 1500 mm of waterproofness, which includes the floor. The 2-person version has a trail weight of 2 pounds 9 ounces and will sell for $379; the 1P is $329, and the 3P is $479.

Sierra Designs Tensegrity (1- and 2-person versions, single-wall, trekking pole supported). Sierra Designs is returning to its roots and re-inventing itself with innovative and functional gear for backpacking. The Tensegrity tents look like a lean-to; they are supported with two trekking poles at the head end and one hoop pole at the foot end, and have a gear storage vestibule at the head end which can be converted to a canopy with two more trekking poles. There is access to the gear storage from inside the tent via a zippered mesh window. Entry into the tent is through protected side doors (only one on the 1P version). The FL version is made of 20 denier coated polyester ripstop and is seam taped; the Elite version is made of nylon fabric coated with silicone on both sides, which will require seam sealing by the user. The Tensegrity 1 FL has a trail weight of 1 pound 15 ounces, and the Elite version weighs 5 ounces less; MSRPs are $320 and $400 respectively. The 2-person version weighs 2 pounds 8 ounces for the FL version and 6 ounces less for the Elite version; MSRPs are $390 and $490 respectively.

Hilleberg Enan (1-person, double-wall, semi-freestanding). The new Enan resembles the Akto, with a single center hoop pole. It’s made of Hilleberg’s new Kerlon 600 fabric, which is a 10 denier triple silicone coated nylon. Headroom is 37.4 inches at the center. It has a side entry, protected by a vestibule. Both ends have a mesh vent that is closable. Trail weight is 1 pound 15 ounces and MSRP is $625.

MSR Flylite (2-person, single-wall, trekking pole supported). The Flylite is another lean-to looking tent; it’s supported by two trekking poles at the head end and one pole at the foot end. The 29 square foot floor is 55 inches wide at the head end tapering to 42 inches at the foot end; headroom is 42 inches. The walls are 10 denier fabric and floor is 20 denier. Ventilation is through mesh panels protected by flaps on the front and sides. Weight is 1 pound 9 ounces and MSRP is $350.

Lightwave Sigma (1- and 2-person, breathable single-wall, freestanding). This breathable single wall tent has a technology story. Its 20 denier nylon fabric is coated on the inside with X-Tex which is a Cocona (activated carbon) coating. According to the designer, Carol McDermott “the activated carbon absorbs the water vapor and prevents it from forming droplets, so the inside tent surface feels dry to the touch. The large surface area created by the activated carbon means that the energy required to keep the water in an evaporative state is much lower, and this results in the fabric continuing to be effectively breathable.” He further explains “this technology is massively more breathable than an eVent tent because eVent is no longer functional when it becomes coated with condensation, while the Cocona technology continues to transfer water molecules to the outside.” The Sigma tents are rated 4-season, have one entry, and headroom is 42 inches. Weight for the 1P version is 3 pounds 8 ounces and 2P version is 4 pounds 5 ounces and MSRP is $649. It would be nice if they can get the tent weights down a pound or so.

Big Sky International Wisp (1-person, single-wall, trekking pole supported). The Wisp will be offered with five fabric choices: 40-denier PU coated nylon (a low cost option), SuprSil (like regular silnylon, only stronger), SuprSil UL SUL (a lighter version of silnylon), SuprSil SUL (a still lighter weight of Silnylon), and Let-it-Por (Cuben Fiber) with weights of XX, 20, 18, 14, and 10 ounces respectively. Entry is from the side though a vestibule. MSRPs range from $150 to $500 depending on the fabric option. I published a First Looks article on the Wisp on this blog in early August.

Six Moon Designs Deschutes Tarp (1-person, single-wall, floorless, trekking pole supported). I had the opportunity to meet with Ron Moak at OR, who showed me his new Deschutes Tarp. Basically it’s a roomy one-person floorless shelter made of Cuben Fiber that weighs a mere 7 ounces. This shelter is not bugproof, but it provides 44 square feet of protected area and 49 inches of headroom. I have used shelters of this type before (the SMD Gatewood Cape and Wild Oasis) and find them very liveable. The difference is the Deschutes is larger, and a floorless shelter is a good option if you hike with a dog. MSRP is $330. A silnylon version is available (13 ounces, $165).

Nemo Blaze (1- and 2-person versions, double-wall, non-freestanding). We found the lightest new double wall tents at Nemo. The Blaze 1P has a minimum weight of 1 pound 11 ounces and the 2P weighs 2 pounds – that’s right a 2-pound 2-person double wall tent! And it’s not skimpy on features and space either. The 2-person version has two side entries with vestibules, floor dimensions of 50x85 inches (30 square feet), and 40 inches of headroom. It attains that low weight by using one diagonal longitudinal hoop pole and hubbed cross pole to support the vestibules, plus use of 7 denier fabrics for the canopy and 10 denier for the floor. The Blaze’s floor dimensions will accommodate two 25-inch wide sleeping pads and has more headroom than the Hornet below. This tent definitely requires some TLC, but from my past experiences its remarkable how strong and durable these fabrics are. MSRPs are $370 for the 1P and $450 for the 2P.

Nemo Hornet (1- and 2-person versions, double-wall, semi-freestanding). How’s this for beating your own record; the Hornet has a similar feature set as the Blaze but weighs slightly less and costs significantly less. The differences are the pole design (one longitudinal hubbed wishbone pole), fabrics (15 denier body, 7 denier fly, 15 denier floor), floor dimensions (the Hornet is narrower at the foot end), and less headroom compared to the Blaze. The 1P version weighs 1 pound 10 ounces and MSRP is $320; the 2P version weighs 1 pound 15 ounces and has an MSRP of $370.

Marmot Force (1- and 2-person versions, double-wall, freestanding). Even Marmot will be introducing new superlight tents. The Force 2P's trail weight is 2 pounds 15 ounces, and it has two side entries with vestibules. The interior is mostly mesh to save weight, the fly fabric is 30 denier ripstop nylon, and the floor is 40 denier. It has a cross pole at the top to provide more interior space and anchor the side vestibules. Floor area is 29 square feet and floor dimensions are 52/38 wide x 86 long. MSRP is $389.

Marmot Nitro (1- and 2-person versions, hybrid, trekking pole supported, non-freestanding). The Nitro (2-person version shown) is a hybrid design (meaning part of the tent is single-wall and part is double-wall) that looks a bit odd, but its functional. The exposed part of the tent body is waterproof, and the interior part is mesh. It has one included strut at the foot end, and the front can be supported with a trekking pole. Trail weight for the 2P version is 2 pounds 5 ounces and floor area is 29 square feet. It has one end entry protected by a vestibule. Fly, canopy, and floor fabric weights are the same as the Force. MSRP is $329.

 

Backpacks

Under backpacks I present a potpourri of new models, new manufacturers, and new innovations.

Ultimate Direction Fastpack 20 and 30. Ultimate Direction specializes in gear for endurance runners, who prefer a pack with lower volume and plenty of pockets to make everything accessible on the fly. Many of those features transfer to fastpacking, which introduce some refreshingly innovative ideas into backpacks. What distinguishes these packs are their vest suspension and well-designed feature set. The Fastpack is available in 20 and 30 liter volumes, which could accommodate an overnight gear kit. I received the Fastpack 20 three months ago for testing and comment, and was immediately impressed with the feature set and vest suspension. The backpanel side of the pack has extra wide shoulder flaps (like a vest) with numerous pockets on them, two sternum straps for securing it over your chest, a removable padded backpanel, and no hip strap. The absence of a hipbelt is surprisingly liberating, as long as pack weight is under about 10 pounds. You wear it instead of carrying it. The frontpanel side had a full-height stretch nylon front pocket plus two stretch side pockets that are reachable. It has s drybag type top closure that attaches to side compression straps, so compression is self-adjusting. Inside there is a hydration sleeve with one center hose port. The front pockets, five of them on the vest flaps hold water bottles, energy bars, and other needed items close at hand. For fast and light trips, it’s really handy to carry energy drink in a chest pocket bottle plus plain water in a hydration bladder. The new for 2015 Fastpack 30 has a HDPE framesheet+foam backpanel, and an internal stretch mesh divider. Both packs are available in unisex S/M and M/L; the Fastpack 20 weighs 24.8 ounces and costs $149, and the Fastpack 30 weighs 26.6 ounces and costs $174.

Camelbak Octane 18X and Pursuit 24LR/Sprite 22LR. The multisport Octane 18X (left) is a nicely designed larger size hydration pack with large easy-access hipbelt pockets, included 3 liter reservoir, and zippered front to allow extra storage; weight is 1 pound 2 ounces and MSRP is $120. The Pursuit and Sprite (right) are mens/womens done-in-a-day packs featuring a polycarbonate framesheet, trampoline backpanel, 100 ounce lumbar reservoir with wide opening for easy cleaning, and numerous outside pockets. Weight is 2 pounds 9 ounces, $150.

More Mountain Hardwear Backpacks Available with an OutDry Lining. Last year Mountain Hardwear announced their first waterproof backpacks, achieved by laminating an OutDry membrane to the inside of the pack. The initial packs are larger volume. Now MH will offer the OutDry feature to three more pack models (Scrambler, Ozonic, and Direttissima) in mens and womens versions ranging from 30 to 58 liters. According to the MH representative, the OutDry lining adds only a fraction of an ounce to the weight of the pack. The packs’ top pocket is not laminated, but does have a PU coating. Pictured is the Ozonic 50.

Granite Gear Virga 26. Granite Gear will be introducing a smaller version of their popular Virga frameless backpack, the Virga 26. The new pack has 26 liters of volume, 100 denier Cordura fabric with 210 denier reinforcements, a rolltop closure, stretchwoven front and side pockets, side compression straps, well-padded shoulder straps, and a webbing hipbelt. Weight is 16 ounces and MSRP will be $120.

Lightwave Fastpack 50 and Ultrahike 60. These are not brand new models but they are new to the US via www.crux.us.com, a US distributor. The Fastpack 50 (left) has aluminum stays, stretch nylon side pockets (no front pocket), zig-zig side compression straps, seams are either welded or seam taped for waterproofness, and each side has a ski holder strap at the base; weight is 2 pounds and MSRP is $240. The Ultrahike 60 (right) is a similar design except the side compression is via a zig-zag cord system. Weight is also 2 pounds and MSRP is $270.

Thule Capstone Backpacks. Thule, a Swedish company known for its car-mounted carrier systems surprised us with a line of new backpacks. The packs are not very lightweight, but we note their innovative frame system consisting of a framesheet plus two tensioned tubes.

Trekking Poles

Not a lot new in the trekking pole category, but we did find an interesting technology story.

Leki Speedlock II Pole Lock. The Leki representative provided us with some interesting information on pole locks. Leki will be introducing their new Speedlock II (left) on their poles in 2015. It’s one-third smaller, 25% lighter, and 20% stronger than their current external lever lock (right). Interestingly, he told us that their internal twist locking mechanism is significantly stronger than an external lever lock. I thought the opposite was true. When he explained it, it made sense: an internal expansion lock has more power than an external compression lock, partly due to the amount of surface area and partly due to the type of force.

Rainwear

As a bonus to this installment, I add the Berghaus Hypersmock 2.0, the lightest rain jacket on the market, made lighter for 2015.

Berhaus HyperSmock 2.0. In my winter 2014 OR Show coverage I reported on this hyperlight rain jacket, weighing just 3.88 ounces according to Berghaus. I got one in size Large to test and found it actually weighs 3.4 ounces (funny how you sometimes wish for less). At summer 2014 OR I found out this jacket will be revised for 2015 and lightened to 2.65 ounces! And it’s claimed to be 100% waterproof. The MSRP is $149. One thing I discovered right away is the jacket is very trim fitting; size Large will layer only over an ultralight down jacket, but no more. More info to come as my testing continues.
