in cold weather without rain, I used it as an additional bottom for a tent, folding it in half - it worked better than with a friend, just an additional single-layer bottom. Some pros: light, compact immediately with stretch marks and pegs and a cover. has loops and grommets (I like loops more - somehow it feels more reliable). Doesn't let water through. Cons: the extension cord of a friend on a 5x3 tent is of better quality - they do not twist, but this is a slight discomfort during installation and assembly, otherwise it does not interfere
