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.

Big Agnes is a small, independent US outdoor brand out of Steamboat Springs, Colorado – a small ski-town that we’ve never visited but which we like to imagine is full of mountain-loving, trail-hiking outdoorsy types. That would make sense, since the company makes some of the best ultralight backpacking gear around, including the award-winning Copper Spur, Tiger Wall and Fly Creek tents. It is kit that has clearly been designed by a gang of folks who love sleeping in the dirt just as much as we do here at WildBounds.
Oh, and if you’re still wondering where the heck that name Big Agnes comes from, we did try to find out. Depending on who you talk to, it’s either an affectionate tribute to a legendary truck drivin’ mountain mama, or a 12,000 foot peak in the Mount Zirkel Wilderness. We kinda like the first one better.
