The Pocket Shower is made of 70D Nylon, the same high quality, wear-resistant, waterproof fabric as our Lightweight Dry Sacks. The seams are fully taped and the roll-top closure has two D rings attached to 20ft of nylon cord, so you can hang the shower almost anywhere. Built into the base is a compact showerhead that operates with an easy-to-use on/off twist mechanism to adjust the flow of water. The black fabric soaks up the sun during the day at base camp for an eight minute or so warm shower.
