Here’s a tarp that can be set up that provides a hassle-free way to collect pure drinking water when camping. The surface can be used not only as a backpacking tarp to add weather protection for your hammock, but it also has a rainwater retention system made up of rain gutters and a suspension system to siphon water out towards the four corners where bottles are attached. When the bottles are full, they pull down the tarp, providing even better protection for the people below. The fabric includes both waterproofing and a heat reflective coating, so if it’s cold and stormy, the tarp can be set up with the reflective side on the bottom, and the dark rain retention side on the top to collect water. If it’s warm and sunny, the tarp can be set up with the reflective side out to help shed some of the heat from the sun. The total system is now available through Kammok.
