This pack is awful. I would not buy this pack. I spent 2 days out in the backcountry in Utah skiing and this pack just does not hold up. If you are looking for an awesome pack check out the Black Diamond Anarchist. It is bomber proof.

Previous review got the high points. I have an older version before they added the hip pockets; those are a nice feature! The neoprene ski carier straps are great. This is one of the most stable ski carrying platforms I've used -- the BCA Stash BC is also a great ski carrier. Hydration system is great; I have never had it freeze up in the 3 seasons I have carried this pack. The side zipper to access the nalgen bottle is very nice; overcomes the usual problem inherent with top-loader packs. Great compression straps so that it carries skis well whether loaded or empty.
But -- there are some problems. The material is flimsy. 2 of my friends all got this pack at the same time. All of us have blown-out seams and/or rips in the fabric. Nice to trade off light weight materials for some toughness, but maybe they went too far. Also it does not carry large loads well. The hip and shoulder straps are very thin. 2 of us were carrying this pack last weekend and both felt the pack was OK handling the load until we added boots & skis for the 7-mile approach. The pack does not support the weight of a 3-day base camp plus skis & boots. Prior weekend with just bivy gear and skinning rather than carrying the skis it seemed OK. I guess anything over 50 lbs is just too much for this pack. Carry less than that and it's great.

Pros:
Nice size for an overnight trip; skiing or climbing. Expands to hold a ton of gear. Lots of compartments make organization a breeze. I like the drinking system. I trust a nalgene in my pack way more than any bladder. Separate shovel compartment, dedicated probe/Shovel handle sleeves, and hip pockets are sweet. And the side zipper makes getting at your gear easy.

Cons:
The padding on the waist belt and shoulder straps is too thin. Overall I would like to have more support for hauling all of the gear this pack can hold. The material is way too thin to take any abuse. Two climbing trips and the pack already has several small rips in it. Definately not a cragging pack.

I think this will make a good ski pack but for climbing it's a dud.

At first this pack was great; light, lots of room, good storage, good hydration system, and comfy. Unfortunately after a year it is destroyed. All the cheapo zipper strings have come off (one ripped off the first day of use) and there are numerous holes in the light yet fragile material. Perhaps with a more gentle owner who also does not rock climb it would hold up better, but in my mind it is not a good value for what you pay (which is quite a lot).
