Use the Black Diamond Skylight Ground Cloth to protect the floor of your Skylight tent when you're pitching it in ultra-rough terrain. Its durable nylon material keeps twigs, pinecones, rocks, and other nastiness from ripping holes in your favorite tent, and it even increases water resistance when camping on snow. The Skylight Ground Cloth clips in place for a secure fit under your tent, so it won't blow away in the wind or gather water in the rain.
