The newest addition to the Sea to Summit Pocket series the Pocket Shower is made of the same heat resistant waterproof fabric and roll top closure as their standard Dry Sacks. Built into the base is a compact showerhead that operates with an easy to use onoff twist mechanism. The twist spout also serves to adjust the flow of water, delivering an efficient trickle to a free flowing shower. Fill the 10 Liter 2.6 gallon Pocket Shower, roll it to close at the top and hang it from two tough Delrin D rings with the 20 feet of lightweight cord provided. The black fabric soaks up sun during the day at basecamp for a warm shower or fill it at the end of the day for a cool rinse.
