Bottom Line Up Front

The Big Agnes Copper Spur HV UL2 is the tent that proves ultralight and livable aren't mutually exclusive. At under 3 lbs for a two-person freestanding double-wall tent, it achieves something that felt impossible a decade ago. After three seasons of heavy use, it's become the default shelter for anyone on our team doing serious backpacking. The price is high and the materials require respect — but the performance justifies both.

Setup and First Impressions

The Copper Spur pitches in about 5 minutes with two people and 7 minutes solo. Two DAC Featherlight poles cross in an X pattern above a central hub that connects both; threading them through the sleeve and clipping the tent body on is intuitive after the first time. The tent is fully freestanding — you don't need stakes to pitch it, though you absolutely should stake it in wind.

The "HV" in the name stands for High Volume, and it delivers. Previous generations of ultralight tents sacrificed headroom for weight. The Copper Spur HV has enough peak height (42 inches) that a sitting adult can change clothes without contorting, and the near-vertical walls mean the floor width is usable from edge to edge.

Three Seasons of Real Testing

We've pitched this tent in the Wind River Range of Wyoming, the Cascades in Washington, the Rocky Mountains in Colorado, and the desert slickrock of southern Utah. Conditions ranged from calm summer nights to a serious thunderstorm with 40+ mph gusts and rain for 18 hours straight.

In the storm: the tent held. The silpoly rainfly shedded water effectively and the seam tape held. One corner stake pulled out in a particularly violent gust — a reminder that proper staking matters — but once reset, the tent was solid. The poles flexed significantly in heavy gusts but didn't break. Big Agnes uses quality DAC poles, and it shows.

In hot weather, the mesh inner does its job — ventilation is noticeably better than fully solid-fabric tents, which reduces condensation. On a warm night with no rain, you can pitch the inner without the fly and sleep under the stars through the mesh ceiling, which is genuinely enjoyable.

The two vestibules are a genuine differentiator. Each door gets its own vestibule, so neither occupant has to climb over the other to get in or out, and gear can be stored on each side. The vestibules are smaller than some competitors (less than 8 sq ft each), but they fit a pair of boots and a small pack.

Verdict

The Copper Spur HV UL2 is the tent we'd buy if we had to choose one shelter for all three-season backpacking. It costs more than we'd like and the materials demand care. But it weighs less, sets up faster, sleeps more comfortably, and packs smaller than any comparable tent we've tested. If you're serious about backpacking, this is the shelter investment that pays off over years of trips.
