A Tyvek Groundsheet and Tent Footprint That Weighs Almost Nothing Your tent floor is the priciest thing you're about to drag over rocks, roots, and pine needles. A Tyvek groundsheet (some folks say ground cloth, some say tent footprint) is a cheap, featherlight layer that takes the abuse so your tent doesn't have to. Ours start at 0.69 oz, and the Jumbo is a DIY-size sheet you cut down to fit your tent. Made by us in the USA. Tyvek is tough, hard to rip, and resistant to mold and mildew. It packs down small and stays quiet in the wind. Small, Medium, and Large also make great camp mats for your shoes and gear.

Spunbonded Fabric weight ~1.62oz/yd 2 (55 gsm) Tyvek Groundsheet FAQ Which size do I need for a tent footprint? Grab the Jumbo (60"x96"). It fits any 2 person tent or smaller. Cut it a few inches smaller than your tent floor so rain doesn't run off the sheet and pool underneath. Is a Tyvek ground cloth waterproof? We call it water resistant, not waterproof. It's built to take a beating from the ground and resist mold, mildew, and dust, which is exactly the job of a groundsheet. Do I really need a tent footprint? If you want your tent floor to last, yes. A footprint is the cheapest repair you'll never have to make, and the Jumbo adds just 7.8 oz before you trim it. What are the small, medium, and large sheets for? Camp mats. Lay out your gear, park your muddy shoes, or give the dog a spot. The corner holes let you stake them down. Can I hang it as a tarp? Nope. The corner holes aren't reinforced to keep weight down, so these are for ground use only. Can I get a custom printed groundsheet? Yep, we make those too. Check out our custom printed groundsheets.
