Jump to: Our Verdict / Features / Specifications

UOG TOP PICK – For Ultralight Comfort With Serious Upgrades: With stronger, lighter, and more waterproof Hyperbead fabric, plus refined space and setup, the updated Copper Spur UL3 maintains its ultralight pedigree while enhancing durability for reliable three-season performance.

Big Agnes says: 

Since its launch in 2008, the award-winning Copper Spur has been our most popular ultralight backpacking tent. Thanks to our proprietary HyperBead™ fabric, the latest Copper Spur UL is lighter, stronger, and more waterproof than ever!

High volume, freestanding design provides ample interior room and the stability to keep you sleeping soundly through the roughest backcountry nights. Fully featured, with design aspects that make the backcountry more comfortable – like multiple gear storage pockets, an awning-style door, and generous vestibule space. When ultralight comfort is the priority, the Copper Spur UL is your ultimate home away from home.

Our Verdict

Light, strong, and more waterproof than ever, the latest iteration of the Big Agnes Copper Spur UL3 refines an already stellar ultralight backpacking tent with new material innovations and design tweaks that improve both performance and durability.

The most significant upgrade is the introduction of Hyperbead fabric, a proprietary material that is 6% lighter, up to 100% stronger, and 25% more waterproof than its predecessor. Unlike traditional DWR coatings that wear off over time, Hyperbead maintains its water resistance without the need for reapplication. It’s also PFAS-free, making it a more eco-friendly choice without sacrificing performance.

Weight savings are minimal compared to the previous model, but the tent feels more robust and reliable in adverse conditions. The pole structure has been refined to increase interior space, and the awning-style vestibules offer excellent versatility, whether you need extra ventilation or additional covered gear storage. The new TipLok Tent Buckle system simplifies setup, securing pole tips, rainfly attachments, and stake-out points in one streamlined mechanism.

For those who loved the previous Copper Spur UL3, this update retains everything that made it a favourite while improving durability and weather protection. It’s still an excellent option for weight-conscious backpackers looking for a roomy, well-ventilated, easy-to-pitch shelter.
