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 it features a roll-top closure. Built into the base is a compact shower head 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 8 minute-ish warm shower.
