Big Agnes Copper Spur UL2 Review
Brand: Big Agnes · Category: shelter · Price: $530 - $600
Buy this if you want the most livable ultralight two-person tent — roomy interior, dual doors/vestibules, and a high-volume freestanding pole system; skip it if you’re on a strict budget or need the absolute lightest pack weight. The Copper Spur HV UL2 is a 3-season shelter (good for spring–fall, not for heavy winter snow) that uses 15D/20D HyperBead fabric — 'D' means denier, a measure of fabric thickness, so 15/20D is very light and needs careful site choice — and it trades a bit of long-term abrasion resistance for weight and interior space.

Complaints
- Thin 15D/20D fabrics require careful site selection to avoid abrasion
- Higher price point around $600 compared to budget alternatives
- Durability concerns with floor and fly in rocky or high-wear terrain
- Poles can be finicky in extreme winds if not fully tensioned
- Vestibules smaller than some competitors for gear storage
- No included footprint, leading to faster floor wear
- Zipper quality varies; some reports of snagging over time
Durability
Big Agnes prioritizes light fabric: the fly and floor are 15D/20D HyperBead nylon — '15D/20D' means the fabric is very light and thin, which saves ounces but is more vulnerable to punctures from sharp rocks or abrasive gear. Multiple reviewers reported floor punctures and faster wear in rocky campsites and recommended using a footprint (not included) to protect the floor. Zipper quality has varied in user reports, with some snagging over time, so treat zippers gently and avoid overloading vestibules. On the positive side, HyperBead’s improved coating increases tear strength versus older PU coatings, so the tent fares better than earlier Copper Spur versions for long-term fabric abrasion — but it’s still a lighter-weight fabric choice than heavier-duty competitors like the North Face Stormbreak 2.
Livability & Space
This tent shines on living space: 29 sq ft of floor area gives a real two-person footprint, and the 40 in peak height (that’s the tallest internal point) makes it comfortable for sitting up and for users up to about 6'4". The high-volume (HV) hubbed DAC NFL/NSL pole geometry creates near-vertical walls, so the space feels much larger than sloped competitors like the Nemo Hornet. Two doors and two vestibules (9 + 9 sq ft) mean each person can access their side and stash a day pack under a rain awning without climbing over a partner. The interior also has generous pockets, a media pocket, and compatibility with a gear loft for organization — small comforts that add up on multi-night trips.
Weather Protection
The fly uses HyperBead™ silicone/polyurethane coated nylon that Big Agnes says is 25% more waterproof, 50% stronger, and 6% lighter than prior coatings — in practice that gives good resistance to steady rain for 3-season use. Being billed as a 3-season tent means it’s built for rain, wind, and moderate storms but not for heavy snow loads or extended winter use. The freestanding hubbed pole system and high-tension brow pole increase stability and headroom, but reviewers note poles can be finicky in extreme winds if not tensioned and guyed correctly. Reflective guylines and included Dirt Dagger stakes help secure it, but expect to spend time running guylines in serious gusts.
Setup & Ease Of Use
The DAC hubbed pole system with Big Agnes's TipLok buckles aims for quick, repeatable setups; the hubbed poles and brow pole lift walls vertically so you get instant living volume once the tent’s up. Setup is freestanding so you can move the tent until you have the best spot, and the included Dirt Dagger stakes and reflective guylines help with nighttime tensioning. Quick Stash doors and a lengthwise compression sack with an easier opening make packing and access friendlier than many ultralight tents. Do note tension matters: if you don’t fully tension the poles or guy out the tent in high winds it can be more susceptible to flexing than some sloped-pole designs.
Who Should Buy This
This is for ultralight backpackers who want two-person comfort — solo hikers who like extra room, bikepackers who need a small packed footprint, and tall users who value the 40 in peak height and gear organization. Don’t buy it if you camp on sharp, rocky ground nightly and can’t commit to using a footprint, or if your budget rules out the $500–$600 price band. Expect tradeoffs: you get great interior volume, quick setup, and a tiny packed size at the cost of thinner fabrics that demand cautious campsite selection, and occasional zipper/pole quirks under heavy use.
Value & Alternatives
With street prices around $530–$600, the Copper Spur HV UL2 sits at the premium end of two-person ultralight tents; you’re paying for livable space, dual vestibules, and the HyperBead fabric. If you want lighter for less money, the Nemo Hornet OSMO UL2 (2 lbs 8 oz, ~$500) shaves a pound but sacrifices interior volume and headroom. The REI Co-op Quarter Dome SL2 (~2 lbs 14 oz, $349) is cheaper and lighter than the Copper Spur but offers smaller vestibules and isn’t as roomy. For users prioritizing durability and price over ultralight volume, the North Face Stormbreak 2 (~3 lbs 11 oz, $240) is heavier but made from thicker fabrics; the Copper Spur wins if you want maximum liveable space per ounce.
Weight & Packability
At 3 lbs 8 oz, the Copper Spur HV UL2 is ultralight for a two-person tent; that weight is light enough that most weekend hikers won’t notice it, but you’ll feel the difference by day three on a loaded thru-hike. Packed down to 7 x 13.5 in, it compresses small enough for a bikepacking frame bag or the top of a loaded pack — that compactness is made more usable by the tent’s lengthwise compression sack. The packed size and hubbed pole layout were designed to shave bulk compared with older Copper Spur versions (the earlier sack was longer and narrower). The tradeoff is the tent isn’t the lightest in class — the Nemo Hornet OSMO UL2 is a full pound lighter (2 lbs 8 oz) if absolute ounces are your priority.
