The Copper Spur UL3 is for three people, or two with a dog and wet gear, who want a door and vestibule each and still want the pack to feel light on the climb. The freestanding structure pitches without staking the corners, so it sits happily on the rock slabs above Jefferson Park, and both doors prop into awnings with trekking poles for a dry porch in a Gorge drizzle. The HyperBead fly and floor carry a 1500 mm waterproof rating with no intentionally added PFAS.
