To extend the life of your Big Agnes Copper Spur UL tent floor we recommend using a Big Agnes footprint. 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. Weighs 10 oz. Packed Size 8 x 5 x 2 inches Featuring our strongest and most durable HyperBead fabric technology in our UL tent line, this proprietary fabric is 6% lighter, 25% more waterproof and 50% stronger without added water repellent chemicals.
