Groundsheet made from polyester coated fabric for the Yellowstone and Yellowstone Airtex square tents. As these tents are mainly used for camping/ sleeping in it makes sense to fit them out with the perfectly sized groundsheet. Designed from tough, hard wearing material, this groundsheet will stop your stuff getting dirty and keep the damp ground shut out where it belongs. It's also pretty good at stopping bugs and creepy crawlies coming at you during the night armed with knives, forks and bad table manners. You know you want one - a groundsheet, not a bug with bad manners and even worse table habits.
