Big Agnes 2025 Latest Copper Spur UL3

Three-season, independently supported, ultralight tent. Since its launch in 2008, the award-winning Copper Spur has been our most popular ultralight backpack tent. Thanks to our patented HyperBead™️ fabric, the latest Copper Spur UL is lighter, stronger, and more waterproof than ever before!
High capacity and independent support design provide ample internal space and stability, allowing you to sleep soundly even on the harshest nights in the wilderness. Fully functional and designed for greater comfort, it features multiple gear storage pockets, a rain-covered door, and a spacious vestibule. When ultralight comfort is paramount, the Copper Spur UL is the perfect temporary shelter.

Featuring the most robust and durable HyperBead™️ fabric technology in our UL tent range. Engineered for season-round durability.

The patented HyperBead™️ fabric is 6% lighter than traditional fabrics, 25% more waterproof, and 50% stronger, without the need for additional waterproofing chemicals.

The EZ Pack storage bag features a large vertical opening and a compression seal, making packing simple and easy.

High-capacity, independently supported structure provides spacious living space and stability – it can be fully set up without the need for fixed corners!

Large, easy-access doors are designed with a dry entry and exit lobby to keep equipment dry.

It features a side entrance and a double-door design, with a doorway and a spacious foyer on each side.

The extended-coverage canopy door can be supported with trekking poles (sold separately) or additional ropes.

The extra-large 3D storage bag provides ample off-floor storage, while ceiling and side pockets offer additional organization space.

Increase ventilation: The front door is equipped with a low ventilation opening, and the top of the tarpaulin has a high ventilation opening. Combined with the double sliding zipper in the front hall, ventilation can be provided from the top or the bottom.

TipLok™️ tent buckles offer safety pole tip securing, rain attachment, tensioner, and retaining rings.

Easy-to-use injection-molded crossbar sockets make setup a breeze.

The Quick Stash door fastener on the tent body makes folding and unfolding the door quick and easy.

Multiple internal loops allow for hanging equipment lofts, accessories, and mtnGLO®️ tents and camping lights.
