Transform your Big Agnes Copper Spur UL3 into the ultimate ultralight shelter system with this custom-designed footprint that unlocks the game-changing Fast Fly setup. When every gram counts on those epic backpacking adventures or bikepacking expeditions, this 207g footprint lets you ditch the inner tent entirely while still providing bomber ground protection through Big Agnes's advanced HyperBead fabric technology with 1500mm waterproof rating. The proprietary Tiplok buckle system creates a rock-solid connection that lets you stake out the footprint, pop in your poles, drape the fly, and buckle down for a shelter that's lighter, faster to pitch, and takes up minimal pack space at just 20 x 13 x 5cm when packed. Whether you're chasing sunrises on alpine ridges or pedaling remote singletrack, this footprint gives Copper Spur UL3 owners (2020 models and newer) the flexibility to go lighter without sacrificing the protection your gear deserves.
