You'll either love it or hate it.

The crampon strap and pick pocket are handy features, but what makes this pack shine is the ball joint belt connecter and swing-arm shoulder straps. The weight of the pack stays in your center of gravity when leaning and reaching. For me, the pack is extremely comfortable. Many will find the lumbar pad odd feeling or uncomfortable. It's one of those "love it or hate it" things.
