Kalais Pack

Now includes hip belt pockets!

For the new Kalais pack we built upon the hugely popular design of our original Kalais and improved it's load support through direct connection of the stay to the shoulder straps and hip belt, increased padding in all body contact areas, and provided on the fly torso adjustment, to each of the four standard torso sizes, allowing the user to fine tune the fit of their pack to their specific body.  From there we continued the improvements by increasing the volume and function of the water bottle pockets and front pocket.  The bottle pockets now comfortably hold two, 1 - 1.5 liter bottles and come standard with a one hand pull closure so you can secure the contents quickly and easily.  

Please note:

  • Most Elemental Horizons backpacks are built to order.  We try hard to ship pack orders as quickly as possible, however depending on the time of year and order volumes lead times will vary.  
  • We have found that, particularly with our framed packs, for individuals who are in between sizes it is best to choose the smaller frame size.  If you choose to go up to the larger size, most times the shoulder straps do not wrap over the top of the shoulder, which can upset the balance of the pack, and the stay is too tall and can interfere with your head's natural range of motion.

Kalais Review
Written by Taylor Drake on 14th Mar 2021

I just finished my first trip with the Kalais, and it was perfect. I couldn't be happier. First class customer service and an excellent product make for a great combination. I'm not an "ultralight" backpacker, but I'm pretty lightweight, with a typical 3-season base weight somewhere around 15 lbs. This trip was heavy, though - 5+ days of food, 6L of water, an 80ft rope (which turned out to be unnecessary, but that's another story), winter conditions, and packing out our waste in wag bags, which I ended up carrying for both my partner and myself. I weighed the full pack at the start, and it was 46 lbs. At the end, it was 45 lbs, thanks to all the human waste (and a little extra trash we found and packed out). Needless to say, the Kalais was maxed out the whole time, except when the water ran low just before we reached a spring to refill. Thankfully, I can report that the pack worked beautifully. Before I bought the Kalais, Matthew spent some time emailing with me to make sure I got the right size, and it paid off. Don't get me wrong - carrying a 45 lb pack for any length of time is not comfortable, period - but it was as comfortable as it could have been. The pack handled the weight extremely well, without any problems. If I needed another pack, I would buy this exact product again.

Review of Kalais pack
Written by Thomas on 7th Nov 2019

I bought the Kalais as a replacement for my previous pack, a Zpacks Arc Haul, with a view towards a higher load limit for upcoming long distance desert hikes. I have taken it out for almost three weeks in Escalante Natl Monument this past October. General: Great workmanship, pack was at my door within slightly more than a week, Matt is great to work with ( he lived up to his reputation). The hipbelt is just great, finely tunable and you can have your pack ride on your hips without discomfort. The sidepockets are huge, holding a 2L and a 1L platypus bottle each, and are easily accessible while wearing the pack. While bushwhacking I lost one bottle, but that’s easily addressed by modifying the necks of a bottle to hook up to a compression strap. The pocket also easily held my Tarptent, which, owing to its length when packed, is impossible to carry horizontally inside the pack. While ordering I had my doubts about the front pocket, but these turned out to be completely unfounded: it was unaffected during bushwhacking and while hauling up the pack on a rope. I spent some time playing with the adjustments of the harness, not because I had to, but more to figure out how comfortable I could make the pack. When the long water carries are in my immediate future I may revisit this, but for the time being the pack is well dialed in for 25 lb loads. The aluminum stay is solid and solidly anchored in the lumbar pad. Coming from a pack with an air gap between my back and the pack, the close contact with the pack takes getting used to. There is practically no ventilation. The material the back panel is made of I found to be a first rate crud collector, needles, twigs etc. while bushwhacking. This also is new to me since all my previous packs had smooth cloth contacting my back. The hipbelt pockets are affixed to the belt and sit, for my taste, far back. It’s not as easy to see what I am looking for as it was on my previous pack. First world problems! While there are several points on either side of the front pocket where gear can be attached, there is no daisy chain on the shoulder straps. I will make a modification there for sure. The three side compression straps as well as the one coming over the top, work well. I wished there were buckles on the side ones so that one could use them to strap heavier items to the outside. Something that one can easily modify oneself, I figure, if and when this turns out to be necessary. Overall, I am very happy with what the Kalais turned out to be, I have not encountered a dealbreaker. I think that for its weight the pack delivers a very good load capacity in terms of both volume and weight.

First In Class

This is a quick review of the Elemental Horizons Kalais pack. I purchased mine this past spring and it is the updated model currently shown on the web site. First, let me say that I’ve never posted a review of any gear I’ve owned, but I feel this pack warrants me getting my thoughts out there. I’ll also mention that I’ve been backpacking for nearly 30 years and have worn many different packs, so I feel as though I have good perspective. I don’t have hundreds of miles on this pack yet, but I’ve hiked with it enough to have a very good feel for its features and performance. The fit & finish and craftsmanship of the Kalais are outstanding. I had Matthew build my pack with the XPac material and I’m very glad I did. This material exceeded my expectations of durability, resistance to water and looks. Also, the inside layer is white so it makes it easy to see in the pack. I recommend the material, but it would be the same great pack if it were built with the other fabric choices. The Kalais is the most comfortable pack I’ve ever worn. My total pack weight doesn’t exceed 25-27 pounds (for a long trip), so I can’t vouch for heavy loads. The suspension transfers the load down to the hip belt and onto my hips. The hip belt is really the star of the show. It’s soft and well padded and the 4 strap adjustment system allows me to wrap it tightly around my hips without any discomfort. The back padding is also soft and comfortable and I’m glad I went with the lumbar pad. The shoulder straps are also top notch. I haven’t experienced any rubbing or hot spots anywhere. Regarding volume, the Kalais is larger than I expected. The main pack bag holds a ton of gear with room to spare. I have no doubt it will hold a week’s worth of food. The side pockets are huge, the largest I’ve seen, and will hold two 1-liter Platypus bottles (probably more). I can reach my water bottles while wearing the pack, which is something I typically can’t do with other packs. The front pocket is bigger than it looks and you can stuff quite a bit in there. There is cordage on the outside of the front pocket which is great for lashing wet clothes. I also really like the design of the pack which is more tall and narrow. That helps when I need to squeeze between large rocks or trees. I hike in the White Mountains, so there can be a lot of maneuvering. I also purchased the hip belt pockets and shoulder strap pocket. The hip belt pockets are also huge (I can fit all my snacks for the day), easy to reach and the two-way zipper pulls make them super convenient to open and close. I use the shoulder strap pocket for my camera and there’s a lot of room in it for whatever you want it for. Overall, given the build quality, suspension, comfort and well thought out design I highly recommend the Kalais. You won’t be disappointed. I’d also like to mention the superb customer service you will receive from Matthew.

Love my personalized Kalais Pack
Written by Judy Young...aka...GrayJay on 14th May 2017

I am a 72 yr old long distance hiker, and this is my 7th pack. It is by far the best pack I've ever bought. It is lightweight, well designed and constructed. The side pockets are ample with a tightening cord. I like the big pocket on the back. I like this pack because it is a top loader & I can easily pack stuff, and then find it when I need it. The harness design is comfortable and easy to adjust the fit. The waist belt is the most comfortably designed, with cinches to fit it to my hips. The best part of buying from Elemental Horizons, was working with Matthew to get a personalized pack. Thanks, Matthew...I am looking forward to carrying my pack when I hike part of the AT this year in NH & ME

Comfortable and light
Written by Jen Carter on 24th Jul 2016

Initially I was skeptical about a no-frills backpack that didn't have a lot of pockets/zippers. But it hasn't been a problem at all (who knew you didn't need all those pockets), and I love the weight that is saved by not having the extra frills. I think this pack is actually easier to pack than my Dana Design pack that I had for years. I was also skeptical about buying a pack over the internet without trying it on. I was comparing this pack to a gorgeous new Osprey lightweight pack that was all the rage in the outdoor stores. The Kalasis blew the Osprey away in terms of comfort, and I'll trade comfort over pretty color any day. The Kalasis didn't have the fancy features of the Osprey pack that at first seemed very tempting, but I eventually realized that the "features" just added weight to the pack. I have taken this pack out for weekend trips as well as week long trips. I don't think that all the stuff I used to take on week long trips before I started doing lightweight backpacking would fit in this pack. But since being lightweight is the whole point of this pack, I think there is plenty of space if that's your goal. I have been thrilled with my Kalasis pack and am very glad that I didn't go for the name brand pack instead. I think the Kalasis is just as well constructed as the name brands, and the bare-bones approach just saves weight which is my highest priority. I highly recommend it!
