Bulletproof sucker! I got it for snowshoeing/cross country skiing and it hold up well to everything so far, knock on wood! It is pretty heavy for its size but extremely well constructed. It has two 1.5" compression straps and a slipproof patch on the front so you can lash your snowboard/snowshoes down and they won't wiggle around. It also has ski tunnels under each side pocket for poles/skis. It is the one pack I've seen that could probably survive falling off the top of the car and being run over by an 18 wheeler.
