The last few months I've been using a 9L daypack. Its just large enough for my hydration bladder, medical / survival kit, emergency poncho, mylar blanket and a few misc.. I think its time to "graduate" to a larger pack..

In addition to my "regulars", space for clothes (+ socks, a windbreaker...) I'd like to have enough space for camp stove, possibly a hammock. It would be nice if it had attack points for trek poles and hydration compatible..

Definitely open to suggestions.. There aren't many options locally, so I'd probably have to order it and hope I won't have to return it and pay postage. I was hoping to stay within a range of about $100-$150..

Also which would be better for bad back? internal vs. external frame..
