Copper Spur UL4

The ultimate ultralight home from home

A lot of ultralight shelters seem roomy enough – but by the time you’ve stashed all your kit inside, unrolled your mat and sleeping bag, and then climbed in, you suddenly seem pretty cramped. Big Agnes’ Copper Spur UL has been specifically engineered to overcome that problem. It is an ultralight, free-standing three-season tent that utilises a high-volume design to ensure ample living space. Updated for 2025 using Big Agnes’ own proprietary HyperBead™ technology that is 6% lighter, 25% more waterproof, and 50% stronger than traditional coatings, providing superior protection and stability. In addition, clever storage incorporating traditional, media, and 3D bin pockets help you to organise your gear without encroaching on your sleep space or your headroom. Use your walking poles or some handy sticks to turn your flysheet door into a useful canopy, which is great for fending off drizzle or providing some welcome shade from the blazing sun.
