Our take on the Big Agnes Copper Spur UL3

The Big Agnes Copper Spur UL3 is a freestanding three-person, three-season backpacking tent that weighs 3.8 lbs and offers 41 sq ft of floor space with 43 inches of peak height. Its HyperBead fabric is claimed to be lighter, more waterproof and stronger than conventional tent fabrics, and dual side doors with two vestibules give each camper a dry entry and gear space. It suits weight-conscious backpackers and couples who want livable room without a heavy shelter. Against rivals like the MSR Hubba Hubba and NEMO Dragonfly, it trades a little floor width for a roomier feel and an awning-style door, and owners rate it highly for space-to-weight.

About the Big Agnes Copper Spur UL3

The Big Agnes Copper Spur UL3 is a freestanding, 3-person, 3-season dome tent for ultralight backpacking. The rainfly and floor use proprietary HyperBead fabric, which is 6% lighter, 25% more waterproof and 50% stronger than traditional fabrics, without added water repellent chemicals.

The freestanding, high-volume design gives generous living space, and the corners don't need to be staked out for a full pitch. It has two side-entry doors, each with its own vestibule. The awning-style doors can be propped with trekking poles (sold separately) or the included extra guylines. Dry entry and exit vestibules keep gear dry.

Inside, an oversized 3D bin pocket provides off-the-floor storage, and ceiling and side pockets add more. Multiple interior loops hold gear lofts, accessories and mtnGLO Tent & Camp Lights. The vestibule doors have low vent capability, there is a high vent on the fly, and double sliders on the vestibule zippers allow venting from the top or bottom. Reflective pre-cut guylines and reflective webbing show up in headlamp light.

Questions and answers

Is the Copper Spur UL3 big enough for three adults?
It is officially a three-person tent with 41 sq ft of floor, but three full-width pads fit tightly. Two adults plus gear is the more comfortable setup.
How does it compare with the previous Copper Spur UL3?
The current version uses HyperBead fabric, which Big Agnes says is lighter, more waterproof and stronger than earlier fabrics. The freestanding layout and dual-door design carry over.
Can it handle winter or snow?
No. It is a three-season tent built for rain and wind, not snow loads. Look at a four-season tent for winter camping.
Does it come with a footprint?
The tent ships with its body, fly, poles and EZ Pack stuff sack. A footprint is sold separately and is worth adding to protect the ultralight floor.
How many doors and vestibules does it have?
Two side-entry doors, one on each side, each with its own vestibule for gear. Total vestibule space is 18 sq ft.
Is it freestanding?
Yes. The high-volume dome pitches freestanding, so you do not need to stake the corners for a full setup, though staking it out adds stability in wind.
