Deuter Race X Air I SL

I bought this as a day pack for a trip to Thailand and I've become so addicted to it I use it every week in the New England White Mountains even in the winter (day trips only obviously). I love the design that keeps the pack OFF your back with the mesh and keeps me from overheating.

I strap crampons/xtra clothes etc on the back of it with a big velcro strap and a crampon bag, and many many things hook onto the straps on both sides. I always overstuff it and it hasn't broken—and there is more mesh that pulls out from a zipper on the bottom to hold extra stuff.

Still, this is a hiking pack just for those who go 'light' (my dog carries extra stuff in her pack for me). This brand works well for short people like me.

This little pack is awesome. Plenty of room for snacks, rain gear, and jacket. 3 liters of water that doesn't taste like plastic. I love it and the SL fit is great!
