    Great pack!

    • Familiarity: I gave it as a gift but have feedback to share

    Got this as a gift and this is what they have to say about it so far: "I love this pack, the fit is really good and comfortable. I have only been using it for training purposes so far on hikes around my area but I am preparing to go to Everest base camp in April and really looking forward to really putting this pack to the test. I have noticed that the suspension system makes it feel like you are not carrying as much as you really are so the support is crazy good! Will do another review update once I use it for my travels!"

    Unreal comfort, especially on warm days

    • Familiarity: I've put it through the wringer

    The perfect 2 or 3 day pack.

    The mesh back panel / suspension is the best made. Two top pockets, a stash pocket big enough for camp shoes or a jacket. and two large hip belt pockets offer plenty of on the go access. I do solo backpacking trips of 3 days, 2 nights with this pack regularly, for longer trips I carry the Aether 70.
    Easily fits a three season bag, one person tent, stove, clothing, food, etc.
    The two trekking pole loops for transport are great, as are the trekking pole fast stow straps ( for scrambles) on the pack's left side.

    I was able to get the previous version discounted, the new version has sleeping bag compartment straps (the old version did not) for attaching a sleeping pad.

    This pack is made for overnights and weekends in comfort while doing big miles.

    Unreal comfort, especially on warm days

    Comfortable, awesome pack

    • Familiarity: I've used it several times

    I've used this pack a couple times now, for 2 different multi day backpacking trips. 50L isn't huge, but if you've got small/lightweight gear then it's plenty of room! I was able to fit my sleeping bag, pad, hammock + straps, tent, clothing and food and water for a 3 day backpack no problem. The AG suspension system is amazing, it hardly feels like you're carrying anything! I'd highly recommend this pack to someone who can pack light, and is looking for a good weekend backpacking pack.

    Good solid pack

      Well, first off this is my first multi day pack. I do pack light. That being said! I love this pack, solid with plenty of space. Super comfy on my hips. Im 5'10 and the M fit perfect! The side pockets are super convenient for water bottles while walking to access them and putting them back in. All around love it. Pretty light as well.
