Most backpacks, in general, do not satisfy my (intense) need for organization. This pack is a dream for any backcountry skiier that is a neat freak (like myself). It is obvious that Osprey put a lot of thought into the design. The compartments are perfectly sized, not to mention, very accessible. The front zips off (almost entirely), to reveal two vertical sleeves (one for my probe and the other for my snow saw), a mesh pocket (for my other snow tools), and plenty of room for a shovel. The top of the pack features a large , fleece-lined pocket that can easily fit my googles and a snack. The back compartment is very roomy (perfect for a couple layers, water, skins, first aid kit, etc.). The hip strap pockets are excellent for more snacks and a cell phone (it is a tight fit, but I can squeeze my iPhone 7 into one). The pack is extremely comfortable (to ski and skin with), low profile, and fairly light. I have yet to use it with a bladder and am interested to see how well the sleeve (on the strap) keeps my hose from freezing. My only complaint is one I've seen from other reviewers, the helmet pocket is difficult to use in a pinch. I can get my helmet to fit (with some effort), but it's annoying if I am making multiple transitions.
