The large stretch mesh front shove-it pockets offer dual entry to stash a jacket, hat, map, or whatever else you want to keep close at hand. Last but not least, the stretch water bottle pockets, external hydration sleeve (reservoir not included), and secure zippered hip belt pockets keep water and snacks easily available. From thru hikes to overnight 14ers, going the distance never felt so good.

  1. AT through hiker

    I love this pack, I just completed an AT through hike with it. It is very comfortable and has excellent access the exterior mesh pockets hold a lot of things you want quickly like water filtration and tp. Zipper waste belt holds all your snacks. Very good design and lightweight. Thanks for making it. on Aug 11th 2018

  2. 99% Perfect

    I am posting the same review I posted last summer on Amazon (where I purchased from). My only update is that you can get some crazy good pricing on this pack nowadays, so be on the look out. That said, I think this pack is a sleeper and since Kelty doesn't quite carry the cachet of some of the other lines (and doesn't get any retail space at the Suburban warrior <clothing>, ahem outdoor store from Kent WA) you don't see enough reviews. So here is mine:

    So I think I might have been one of the first to buy and use this new pack from Kelty so I figured a review would help. This is a great pack with 2 minor flaws. I recently completed (2) long 14 and 20 mile hikes over challenging terrain (Presidential Traverse). I carried about 23lbs with water and food. The pack did this perfectly. The harness and adjust-ability were as good as any of my other Gregory packs, only this one is much lighter. The real game changer with this Kelty is the "shark mouth opening" and full front zip. It really is a fantastic idea/feature. In the White's we had ever changing weather requiring adding/shedding clothes and full rain gear all weekend. The Kelty made this a breeze. My 2 buddies struggled digging into packs and at times, choose not to reach for something (clothes, a Coke, etc) due to the challenge of digging things out. The Kelty allows for a very easy, full opening making gear swaps the simplest I have ever had in 20+ years of backpacking. I really can't say enough good things about this pack. (Update, one of those buddies scored a great deal on the Woodbine from Amazon)

    2 minor flaws - The tiny strap that is intended to hold your hydration bag is too small. Like way too small. Luckily a Camelbak has a large built in flange that basically hangs on the internal sleeve and held it fine. If I had to rely on the little piece of velcro, it would have been a mess. There are 2 additional hooks on the pack, but these do not work with the Camelbak hydration bag. At least not without modifying it. A longer/beefier velco strap would be a simple solution and well worth the extra 2 grams...

    The way the pockets/hipbelt/bottom of the bag all form a kind of single piece of gear make it very difficult to keep a rain cover on the pack. There just isn't any nook/crease on the bottom for the cover to bite into. Hopefully this makes sense. An included raincover with some velcro or even some sewn on tabs or something from Kelty would be nice. My cover is now <unfortunately> somewhere on the bottom of Mt Washington after a 60+ mph wind took it away like a kids balloon.
