To extend the life of your Big Agnes Copper Spur HV UL2 Bikepack Tent floor, we recommend using a Big Agnes footprint or ground cloth. 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 the footprint, tent fly, poles, and stakes.
