To extend the life of your tent floor, we recommend using a Big Agnes footprint or ground cloth. The Crag Lake SL2 Footprint features the same 100% recycled fabric used in the Crag Lake, and enables you to pitch a lightweight, Fast Fly shelter while leaving the tent body behind. The Fast Fly configuration requires the footprint, tent fly, poles, and stakes. Features: - Made using 100% recycled fabric for reliable protection that's easy on the environment - Lightweight protection from moisture, sharp objects, and dirt
