Quick verdict: The Big Agnes Copper Spur HV UL2 is one of the most livable ultralight backpacking tents on the market. At just over 3 pounds, it delivers a rare combination of low weight, real headroom, and reliable weather protection — but it comes at a premium price and demands a gentle hand in the backcountry.
If you’ve spent any time researching backpacking tents, you’ve run into the Copper Spur. It’s been a staple on America’s long-distance trails for years, and for good reason: few tents balance weight and comfort as well as this one does. This review breaks down what it’s actually like to use, who it’s right for, and where it falls short.

What It’s Like to Use
The first thing you notice stepping inside the Copper Spur HV UL2 is how much taller it feels than its weight class suggests. The near-vertical sidewalls and ridge pole create real usable space near the head end — you can sit up, change layers, and dig through gear without constantly brushing the ceiling. Used solo, it’s genuinely roomy. With two people, it’s more of a snug fit: you’ll find yourself angling your shoulders around the sloped walls, and sitting up at the same time becomes a bit of a squeeze.
Setup is fast thanks to the color-coded clips and pre-bent pole sections, and the freestanding design means you can pitch it on rock, sand, or hard-packed dirt without needing a perfect staking situation. Weather protection has held up well for most users in wind and rain, though the single ceiling vent means you’ll want to keep an eye on condensation in cold, humid conditions.
One detail worth flagging: the tapered floor (52 inches at the head, narrowing to 42 inches at the foot) can get genuinely tight if you’re using two standard rectangular sleeping pads. If that’s your setup, the Copper Spur HV UL2 XL — which uses a fully rectangular footprint — is worth the extra cost and few ounces.
Who Should (and Shouldn’t) Buy This Tent
Buy this if: You’re a backpacker who wants to minimize pack weight without sacrificing comfort at camp. It’s an excellent choice for thru-hikers, weekend backpackers, and bikepackers who value a compact packed size and fast setup.
Consider something else if: You’re extremely budget-conscious — there are solid 2-person tents for half the price if weight isn’t your top priority. Hard-core ultralight backpackers chasing the lowest possible weight may also prefer a semi-freestanding option like the Big Agnes Tiger Wall UL2, which trades some livability for roughly half a pound less.
Copper Spur HV UL2 vs. the Alternatives
Compared to the MSR Hubba Hubba LT 2, the Copper Spur is lighter and slightly more livable thanks to its steeper walls, while the Hubba Hubba counters with a true rectangular floor (no taper) that some campers find more practical for two sleeping pads.
Compared to the NEMO Dagger OSMO 2P, the Copper Spur is noticeably lighter, but the Dagger offers a wider rectangular floor plan and more durable fabrics — a better choice if you’re hard on your gear or prioritize space over weight.
Frequently Asked Questions
Is the Big Agnes Copper Spur HV UL2 freestanding?
Yes. It uses a fully freestanding pole structure, meaning it doesn’t require trekking poles or a perfect staking setup to hold its shape — though staking it out is still recommended for a taut pitch in wind.
How many people actually fit comfortably in the UL2?
It’s officially a 2-person tent, and it works well for two people lying down. Sitting up at the same time, or using two wide rectangular pads, is where it starts to feel tight — many couples upgrade to the UL2 XL or UL3 for extra room.
Is it a 4-season tent?
No. The Copper Spur HV UL2 is a 3-season tent, ideal for spring through fall. It performs well in moderate wind and rain but isn’t built for sustained winter conditions or heavy snow loads.
How does it pack down?
It compresses to about 7 x 13.5 inches, small enough to fit in most backpacks or even strap to a bike for bikepacking trips.
