I bought this hoping for a pack, plain and simple, and that is exactly what is. A darn good pack. First off the shoulder harness is outstanding for a pack of this size, super stable, and comfortable all day and even with alpines strapped on. The size is perfect for everything you need for a day. I can pack my camelback, shell, 300 wt fleece, lunch, extra socks and extra mitten liners into the pack with no problems at all. Also because of its narrow profile one can sit normally on chairlifts even with the pack stuffed. The material is more or less bomb proof. I've skied with it for the better part of a season, as well as used it as my book bag for a semester (not really suggested use, too narrow for multiple text and note books) without any noticeable abrasion or wear. And for those of you who have razor blades for ski edges, that diagonal stripe is extra reinforcement. On top of all this the material is more or less waterproof. Skied three days in snain (indecisive snow/rain) and while I was more than damp at times, everything in the pack stayed pretty dry (ended up dampened once, though this is attributed to a pair of stowed, soggy gloves rather than leaking). The only negative I can think of is the way the lid pocket sits. When its REALLY stuffed, it gets in the way of strapping skis on over it. Over all, though I love this thing. It would not at all be an exaggeration to say that this is the best pack I've ever bought and it should see service through all four seasons for many many seasons to come.
