I have one of the pocket backpacks from EB. I got it free some time ago in an order. Used it so much I blew the bottom out. Great for basecamp style backpacking trips. Stuff in a front pocket for the 10 mile hike in, setup basecamp and then hike to all the fishing lakes and slay some trout with your little pocket daypack. I wore it down to literally nothing but strips of nylon and destroyed zipper, so the Maxped Rolly Poly backpacks are on the wishlist. In a long term survival scenario, those drawstring bags would make for a great hunting/gathering bag-lash on a bottle of water and go digging for shrooms and roots.
