The Medium Outfitter bag is a great choice for all your gear on a summer trip. It is large enough to hold a sleeping bag, and clothes. Keep one ready in the back of the pickup for a quick change of clothes, or for emergency hypothermia gear, or to have a sleeping bag ready for the long drive across Nevada.
Radio frequency welded D ring patches are what hold the Welded Stainless steel D ring in place. There is a heavy duty Boat handle that you can use to carry or even throw it off of your raft on to shore. All straps are sewn to either the d ring, or the PVC web at the top. The polyethylene stiffener is used along with a welded webbing around the top to make the most effective seal without having a lot of hassle involved with other dry bag closure types like zip locks or zippers.
