Serious campers and backpackers, this Catoma Burrow groundsheet is an absolute essential for protecting your tent and staying comfortable in the backcountry! Made from durable 70D hybrid-lite ripstop material, this groundsheet adds a crucial extra layer between you and whatever terrain you're camping on - rocks, roots, damp ground, you name it. The brilliant design lets you pack it down with your Burrow shelter, storing everything in the same bag if you want to keep things compact. It attaches securely to the existing corner clips and has Velcro that wraps around the fiberglass poles to ensure it stays exactly where you want it. At just 5.6 ounces, you barely notice the weight penalty, but the protection and added waterproofing are absolutely worth it. The floor area measures 90 inches long by 33 inches at the shoulders tapering down to 25 inches at the feet - perfectly sized for the Burrow system. But here's the really cool part: the grommet attachment points make it compatible with the wolverine/armadillo fly kits and the badger, meaning you can use the groundsheet and fly kits as a standalone ultralight shelter without even bringing the main Burrow tent! That's some serious versatility for when you need to go super light or want multiple shelter options. The coyote brown color blends perfectly with natural environments, and the quality construction feels built to handle rugged use. Definitely a smart addition to your ultralight camping setup that extends the life of your shelter while adding comfort and protection!
