The Big Agnes Tiger Wall UL2 Bikepack Footprint is a durable groundsheet for underneath your Tiger Wall UL2 Bikepack Tent. The nylon ripstop fabric features 1200mm PU/silicone coating, helping to keep groundwater from seeping into your tent. It'll also protect against dirt, grime and pokes from sticks, which means less clean up when you return home. The Big Agnes footprint also enables you to pitch a lightweight, Fast Fly shelter while leaving the tent body behind. The Fast Fly configuration requires just the footprint, tent fly, poles, and stakes.
