The new Kalais pack is a smaller version of Elemental Horizons’ Aquilo pack, which received the
coveted Highly Recommended rating from Backpacking Light Magazine
(subscription required). The Kalais at 2920 cubic inches (size Medium) is about
600 cubic inches smaller than the 3587 cubic inch Aquilo. The frame and
suspension system are the same but the feature sets differ in order to downsize
and lighten the Kalais, and tailor it to its intended user.
The new Elemental Horizons Kalais (manufacturer
photo and specifications) has 2920 cubic inches of total volume (size Medium)
and weighs 26 ounces. Cost is $190.
Description
As the following photo gallery shows, the Kalais is a
traditional design. It’s constructed of 210 denier Dyneema ripstop in high wear
areas, 70 denier coated ripstop nylon in the body, and spacer mesh for padding.
Sidepanel view:
Each side of the pack has a durable mesh pocket and three compression straps.
Inside the pack, there is a large sleeping pad sleeve to use
a partially inflated sleeping pad (or closed cell foam pad) to provide
additional pack rigidity to facilitate weight transfer. It can also accommodate
a hydration bladder (two hose ports are provided).
Elemental Horizons offers the Kalais in three unisex sizes
with a choice of three hipbelt sizes. Options include a removable curved
aluminum stay, sit pad, hipbelt pockets, and sidepanel mounted hydration sleeve
with zippered storage pocket (0.8 ounce).
Assessment
The short answer is the Kalais is one of the best backpacks
I have ever tested, and I have tested a lot of packs. As with the Aquilo, Elemental
Horizons got (almost) everything right the first time, and the Kalais is
another winner.
The volume of the Kalais at 2920 cubic inches is in the
“sweet zone” of 2500-3000 cubic inches preferred by many lightweight
backpackers. It has a bit too much volume for ultralight backpacking, but if
you consistently carry over 20 pounds, and rarely carry over 30-35 pounds, this
is the pack for you. For that type of use, the 26 ounce pack weight beats most
every comparable pack in its category, except the Gossamer Gear Gorilla and Six
Moon Designs Swift. The weight of the size Large pack I tested is 31 ounces
with the optional stay.
The Kalais will function well for ultralight backpacking
because the combination of its internal pad sleeve and three compression straps
on each side will provide all the volume reduction and compression capability you will
ever need. However, its 26 ounce weight is overkill for carrying sub-20 pound
loads that a 12 ounce frameless pack will carry almost as well.
I tested the Kalais on several hikes carrying loads of 16,
25, 25, 32, and 35 pounds, all with the tubular frame inserted, and the heavier
loads (25 to 35 pounds) with a partially inflated Klymit X-Lite pad in the
internal pad sleeve. Basically I tested the Kalais with heavier and heavier
loads to determine its limits.
With a 16 pound load I hardly noticed the pack was there. In
a previous project I found that a removable stay significantly improves weight
transfer and carry comfort for loads over 15 pounds.
The Kalais carried a 25 pound load surprisingly well. I
noticed the weight, but the pack transferred all of the weight to my hips. It
was at this point that I discovered that the Kalais’ four-pull hipbelt
tightening system makes a big difference for carrying heavier loads. By
separately tightening the upper and lower pulls, the top and bottom of the
hipbelt can be tightened separately, which conforms the hipbelt to the hips and
prevents it form slipping under heavy loads.
I further tested the Kalais with a 35 pound load, the
maximum recommended comfortable weight, and found the same result – the hipbelt
did not slip, and the pack still transferred all of the weight to my hips.
The four-pull hipbelt tightening system on the
Kalais is remarkable, it allows you to tighten the top and bottom of the wide
hipbelt separately, conforming the hipbelt around the hipbone, allowing the
pack to comfortably carry heavier loads, with total weight transfer, and not
slipping off the hips.
Elemental Horizons uses a removable contoured aluminum stay
that is similar to the one used by Gossamer Gear and Six Moon Designs, but its
integration into the pack is much better. Rather than a simple straight sleeve
on the inside of the backpanel, the stay is more solidly anchored at the top
and bottom of the pack, so it transfers weight to the hipbelt better, as my
testing results indicate.
The Kalais is not as robust a pack as many sub-3 pound packs
targeted to lightweight backpackers from other manufacturers, but it does fill
an important niche. For backpackers who consistently carry loads between 20 and
30 pounds, the Kalais is an excellent choice; it’s 0.5 to 1 pound lighter than
many other lightweight internal frame packs and does the job just as well, if
not better.
What’s not to like? Three things:
- The shoulder straps are a bit narrow at 2.25 inches, especially if you use the Kalais as a frameless backpack. For me, the narrow shoulder straps were not a problem when carrying the pack with the frame in because the pack effectively transferred all of the weight to the hips, so the shoulder straps mainly provided stabilization.
- Water bottles fall out of the side pockets when you bend over. This could be fixed by making the pockets wider at the bottom so they don’t pop out.
Quite likely Elemental Horizons will address these issues,
and if so I will add an update to this article.
Overall, Elemental Horizons simply gets (most) everything
right to create a remarkable smaller volume removable frame backpack for
lightweight backpackers. It’s well designed and constructed, durable, fits
well, comfortably carries a sizeable load, and its volume adjustment capability
is outstanding. In response to the question of: “if I were to purchase only one
pack, which one would serve most of my needs?”, the Kalais would be one of only
a few packs I would recommend.
Addendum May 29, 2012
In response to my review comments, Elemental Horizons has corrected the problem with water bottles falling out of the side pockets by widening the bottom of the pockets so the bottles now sit deeper in the pockets, as shown in the following photo.
With the bottom of the side pocket widened, a water bottle fits much deeper and is more secure, also the pocket volume increases a bit. Compare this to the previous photos above. Note that the standard pack color is red, not purple as shown
Elemental Horizons will try to accommodate custom color and feature requests; email Matthew Lagas-Rivera at matthew@elementalhorizons.com with your requests. I am very impressed with the quality of his designs and construction, and attention to detail.
Overall, the Kalais, while quite lightweight, is not the very lightest 3000 cubic inch backpack available, but (in my opinion) it has the best balance of lightweight, fit, features, comfort, and weight carrying ability of all the packs I have tested to date.
