Big Agnes Copper Spur Ultralight Tent Review: Lightweight Backpacking Shelter with Impressive Setup Speed

Introduction

The Big Agnes Copper Spur Ultralight represents a significant step forward in accessible ultralight shelter design. This tent delivers impressive weight savings without sacrificing the interior comfort and ease of use that matter on multi-day trips. The standout feature is how quickly it pitches, even for someone setting it up for the first time.

Setup Speed and Ease

The most striking aspect of the Copper Spur UL is how straightforward the assembly process is. The pole system uses a simple four-legged configuration that clips together without requiring tension or complex alignment. The color-coded system helps, but the design is intuitive enough that you can pitch this tent in under five minutes without prior experience.

The fly sheet attaches via a tension bar running across the top of the poles, which pulls the entire structure taut. Velcro tabs keep the fly separated from the inner tent, reducing condensation issues. The dual-door design means both occupants can exit independently, and the doors feature multiple zip positions, allowing you to open just the lower section in bad weather or roll the entire door back for ventilation.

Interior Space and Storage

For a two-person ultralight tent, the Copper Spur UL offers surprising volume. The floor dimensions measure 224 cm long by 132 cm wide, with a height of 102 cm. The pole configuration creates usable width even at the sides, so you can sit upright without hitting your head, which is a genuine advantage over older tent designs that taper sharply.

The tent includes abundant storage throughout. Multiple pockets line the interior walls, large enough to hold drying gear, headlamps, books, or water bottles. The two porches provide additional space for packs and equipment, keeping the sleeping area uncluttered. The mesh construction throughout the inner tent maximizes breathability, which matters significantly in warm conditions.

HyperBead Waterproofing Technology

The most significant change from the original Copper Spur to this UL version is the new fly sheet fabric. Big Agnes introduced HyperBead, a proprietary waterproofing system that is inherently waterproof at the molecular level and requires no reproof treatment over time. This represents a meaningful shift from traditional waterproofing approaches that degrade with use and require periodic reapplication.

HyperBead is also PFAS-free, meaning it does not rely on per- and polyfluoroalkyl substances for water repellency. The fabric is 6% lighter than traditional options, 25% more waterproof, and 50% stronger. The hydrostatic head rating of 1,500 mm on both the fly and floor is more than adequate for typical backpacking conditions. The fabric also resists stretching when wet, which prevents the sagging that can cause the outer fly to contact the inner tent and create condensation dripping.

The 15D nylon with 20D solution-dyed ripstop construction keeps weight minimal while maintaining durability. The inner tent uses 15D polyester mesh, which contributes to the overall breathability of the shelter.

Ventilation and Weather Adaptability

The tent includes vents at the top that seal when conditions are windy or cold and open with their own small pole when you need additional airflow. This design allows you to manage condensation actively without adding significant weight.

A notable feature is the ability to remove the fly sheet entirely on clear nights, transforming the tent into a large bug net. You can fold back one half of the fly for partial coverage, allowing stargazing while retaining some weather protection. This flexibility is particularly valuable for summer backpacking trips where weather is stable.

Weight and Packability

The two-person version weighs 1.37 kg in standard configuration and can be stripped to 1.18 kg if you leave behind non-essential components. The pack size is exceptionally compact at 50 cm by 11 cm, making it ideal for bikepacking and ultralight backpacking where space in your pack is at a premium.

Big Agnes also offers a three-person version at 1.72 kg (strippable to 1.52 kg), with dimensions of 229 cm long by 178 cm wide. This provides more width without adding proportional weight, making it a viable option for those who want additional space without moving to a heavier shelter category.

The pegs included are high-quality and pull out cleanly. Eight pegs come standard, though you may need additional pegs if you plan to use all the guy lines. A footprint is available separately and adds minimal weight while extending the tent’s lifespan if you use it frequently on rough terrain.

Conclusion

The Big Agnes Copper Spur Ultralight is a well-executed ultralight tent that balances weight, comfort, and ease of use. The fast setup time, spacious interior, and new HyperBead waterproofing make it a practical choice for backpackers and bikepacking enthusiasts. Whether you are planning multi-day treks, car camping trips, or lightweight bike tours, this tent delivers genuine value without requiring you to sacrifice comfort for weight savings.
