The new burrow groundsheet gives you an extra layer between you and the rugged terrain. We designed it to be able to pack down with your burrow so you can store it inside the same bag if you want. The groundsheet will attach onto the existing corner clips as well as Velcro around the fiberglass to pole to insure it won't come undone. Grommet attach points at the ends so it is compatible with the wolverine/armadillo fly kits as well as the badger. So when your mission calls for ultralight gear, the fly kits and groundsheet can be used as a stand-alone structure without the burrow as the base tent.
