Big Agnes Copper Spur UL2 Review: The Roomiest Freestanding UL 2P Tent at Its Weight

The HV (High Volume) designation means more vertical walls compared to the standard Copper Spur line. For two adults, this translates to usable headroom at the center of the tent and a floor plan that can fit two 25-inch sleeping pads side by side. Switchback Travel describes the interior as offering impressive livability for its weight, and OGL lists it as a top-performing UL 2P design.

By comparison, the Tiger Wall UL2 and NEMO Hornet Elite Osmo 2P taper more aggressively toward the edges, which creates a snug-for-one situation when two adults are inside. The Copper Spur gives both occupants room to change clothes, organize gear, and sit up without pressing against the mesh inner.

Condensation is the honest trade-off in any double-wall tent with an all-mesh inner, and the Copper Spur is no exception. The mesh allows airflow and prevents warm, moist breath from being trapped inside the sleep space, which is a genuine benefit over solid-inner designs. The cost is that mesh provides no barrier between sleeping bags and the fly interior. On cold nights with high ambient humidity and no breeze, condensation accumulates on the fly's inner surface and can drip onto gear or transfer to sleeping bag shells that press against the mesh walls.

In wetter climates like the Pacific Northwest, the Smokies in fall, and high-humidity settings in general, owners consistently note needing to manage this actively: cracking both vestibule doors an inch or two overnight to promote airflow, keeping sleeping bag insulation away from the mesh walls, and shaking the fly clear of pooled moisture before packing. In dryer intermountain climates, condensation is a minor nuisance. In consistently humid environments, it requires deliberate management to keep sleeping gear dry.

The fly and floor use a thin, lightweight nylon ripstop at the light end of 3-season tent fabrics. For comparison, the MSR Hubba Hubba NX uses a heavier floor construction that absorbs rocky campsite abrasion with less risk of puncture. On the Copper Spur, a footprint is not optional on rocky or abrasive terrain: owners who skip it on granite slabs and coarse gravel report surface scuffs, micro-abrasion, and in some cases small punctures after one or two seasons of regular use. For maintained tent pads and soft soil, the floor holds up to normal use.

The door zippers are the most commonly cited long-term wear point. On heavily used UL tents in this weight class, the slider coils stretch and begin to separate after extended use, typically after three or more full seasons of regular trips or one to two seasons on a thru-hike schedule. This is a category-wide pattern, not unique to the Copper Spur. Big Agnes covers zipper failure under warranty, and long-term owners consistently report that warranty service is responsive: repair or replacement rather than store credit, with fast turnaround.

The pole hub where the three DAC shafts converge at the apex is a stress concentration point under repeated wind-flex cycles. Under normal sheltered 3-season use, the hub holds up for years without issue. Owners who regularly camp in high-wind-exposure sites or push the tent beyond its 3-season design range have reported stress cracking at the hub junction over multiple seasons. If you plan on exposed or high-wind camping regularly, this is worth monitoring.
