As a Complete "Bug Out Bag" I Keep my camping gear ready to go with a Duffle bag of clothing aswell. Soon Im going to Include a smaller satchel with more Urban based tools and safety items for a more complete Kit. As For multitools I have a Leatherman Kick I Often EDC and plan to Have on my hip with a Fixed blade at all times on Campouts and hikes. The Pliers are there cuz they were Free and makes the kit feel more complete to me if I end up without the leatherman.

As For Shelter Im still pondering on this Im sure the smallest of the AMK Bivys would fit in place of the Powder. I may go with a Poncho since they are often thinner when purchased then the spaceblankets.

As For puritabs I may aswell throw in my Coghlans stuff ( http://www.coghlans.com/products/drinking-water-treatment-9586)

Im not to big into the water purification tablets but these were free aswell so might aswell.
