    Pretty much evil

    • Familiarity: I've used it several times

    This pack has a main body and an extension above that to accommodate the extra volume it claims, as the "75". The extension is terribly useless, as it bulges forward into your head and makes walking upright with a full pack almost impossible. Even with very light items like a jacket or rain fly tucked into the top, the compartment that lies above the main frame of the back smushes forward into your neck and head. The waist belt clips are a joke. One trip on an airplane and they were smashed. The waterproof zipper for the front and brain compartments are terrible. Whether the compartment is super full or empty and slack, they split open from the top, base, and center. Overall a total piece of crap. If you need a larger pack, look elsewhere. If you love the idea of this pack, try the smaller version, and carry replacement clips at all times. Really disappointing.

    Hip straps

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

    I bought this for my mom as a weekend hiking pack when we go together. I bought this pack for her because she has hip problems and the hip strap is made to swivel to allow for the natural movement of the pack and make it more comfortable for longer trips. When it comes to the zippers she has had a few issues with the zippers on the brain getting quite easily. Other then that one issue the pack is holding up very well. She has had it dragged against rock accidentally dropped it down a scree field. All in all a very durable pack and comfortable on the hips as well.

    Bad zippers, amazing pack

    • Familiarity: I've put it through the wringer

    I've used this for 3 to 4 day backpacks and wilderness climbing trips in the CA Sierras this season, enough to provide a comprehensive review. Like reviewers of the 65 liter version said, the zippers are a problem. I found that if there is tension on the zippers when you zip them, they misalign and then unzip the creepy way. In other words, if the pack is bursting and you try to squish-and-zip at the same time, no bueno. The good news is (so far) if you avoid this (the cinch straps happen to be expertly placed so you can cinch down the pack first and then zip, working around the straps) they are reliable and from I can tell (severe weather hikes tested), they are even waterproof. My only other gripe is that I wish the pockets on the hipbelt were bigger. But that is because my camera and cell phone are too big. First world problems. Now for the good, the oh so good, it makes all the other issues nondealbreakers: the swiveling hipbelt. I have major, chronic hip injuries, a torn soas, 3 herniated disks in my lower back... yeah. Little did I know how freeing it is to be able to move your hips even with a heavy pack on! I've loaded mine up with a full climbing rack plus 3 nights of backpacking gear, and all the extra shoes and stuff involved, weighing around 50 pounds, and yes its heavy but given that, I am dancing on clouds. I have had way more fancy packs, this beats them all.

    Bad zippers, amazing pack
