Here's what other sites are saying:
Sleeping under the stars is all gravy if the weather cooperates, but rain can spoil your snooze party right quick if you're caught unprepared. With the Ultimate Survival Technologies BASE Hex Tarp, it'll be your own fault if you get soggy, since it weighs just a pound and provides full shelter for one person, making it an essential for every emergency kit and ultralight backpacker. If you'd rather, you can use it as a groundsheet, insulating blanket, or emergency signal, since one side has an aluminum coating to reflect heat and light.
