Most of my published treks are hut-to-hut, so I do not carry a tent on Alta Via 1 or TMB-style routes. For camping treks — Skye wild camps, Cederberg overnights, or any route without rifugio beds — the Copper Spur HV UL3 is the three-person tent I recommend when two hikers want gear vestibules and headroom without MSR-class bulk.
My experience on the trail
I have not slept in a Copper Spur HV UL3 on a published HikingWithLee trek — my multi-day routes are overwhelmingly hut-based. I have pitched it on shakedown weekends and loaded it against MSR Hubba Hubba and REI Half Dome kits for the camping sections of our buying guides.
What stands out immediately is how much interior volume you get for roughly 1.5 kg packed. The near-vertical walls feel closer to a small room than a coffin-shaped backpacking tent. Dual doors mean nobody crawls over a partner at 6 a.m. when you are packing for a wet Skye morning — that alone justifies the UL3 over many two-person tents when two people share.
Who it's for
Two campers who want three-person floor space and dual vestibules without carrying a 3 kg dome. Ideal for couples, friends, or a parent with a teen on week-long wild-camp or festival-adjacent hiking routes.
Also suits three close friends on fair-weather trips if everyone packs light — treat the rating as comfortable for two plus gear, not three adults with full camping kitchens.
Not the right pick for winter mountaineering, sustained gale exposure, or solo ultralight hikers who should look at Nemo Hornet Elite or Zpacks Duplex-class shelters instead.
Weight & footprint
- Trail weight
- ~1.48–1.59 kg (3 lb 4–7 oz) depending on stakes and stuff sacks — verify the exact figure on your retailer listing before comparing against MSR or REI.
- Packed size
- ~48 × 16 cm — long but slim; fits vertically in most 40–50 L packs if you strap the pole bag externally on smaller daypacks.
- Floor dimensions
- Three-person rating with high-volume architecture — real-world sweet spot is two sleepers plus packs in vestibules, not three full-width pads and duffels inside.
- Vestibule space
- Dual vestibules keep muddy boots and stove kit outside the inner on cramped platforms — critical on Scottish bothy-adjacent wild camps where the inner stays dry.
Key features
High-volume architecture
Near-vertical walls add usable headroom and shoulder space compared with older Copper Spur generations — you sit up to sort food without elbowing the mesh.
Dual doors and vestibules
Two entries and two gear porches — no crawling over a partner for midnight bathroom runs on shared camping treks.
Color-coded pole clips
Hub-and-pole system with matched colours speeds first-time setup when light is fading on day six of a route.
Ultralight fabrics
DAC Featherlite NSL poles and lightweight fly/inner keep weight in the same class as premium two-person tents while offering more floor area.
Ventilation
Multiple mesh panels and low vents reduce condensation on mild, damp nights — still pitch with fly tension in wind; no tent ventilates in a horizontal gale.
Freestanding inner
Pitch the inner first on rocky sites, clip the fly after — helpful when ground is too hard for full stake-out on granite slabs.
Setup and livability
Expect 8–12 minutes first time, faster once the colour-coded poles are muscle memory. The freestanding inner is handy on rocky Scottish or Cederberg platforms where stakes are unreliable.
Inside, the layout rewards two campers who store packs in vestibules: keep cook kits and wet boots outside, sleep clothes and inflatables inside. Headroom is enough to sit upright at the door end for morning coffee — a noticeable upgrade over tapered two-person domes on multi-night camping treks.

Weather and durability
Handles three-season rain and moderate wind when pitched with proper stake-out and guy lines — the fly needs tension, not a loose drape, on exposed Cederberg ridges.
Not a four-season bombproof shelter: horizontal rain driven by strong wind will test any ultralight fly. For exposed winter camps or sustained alpine storms, step up to a sturdier mountaineering tent or plan hut/bothy nights.
Fabrics are lightweight by design — treat zippers gently and dry the fly before long storage to maximise lifespan.
How it compares
Hubba is the classic two-person benchmark — lighter for couples who do not need the UL3 floor plan. Copper Spur wins when two campers want separate doors and vestibules without upsizing to a heavy family dome.

Read full reviewTrade-offs
- Premium price for a three-person ultralight — couples who never need the extra floor space save money and weight with a tight two-person tent
- Packed length is awkward in small daypacks; ultralight solo hikers pay a weight penalty versus Nemo Hornet Elite or trekking-pole shelters
- Light fabrics and stakes assume careful use — not ideal for abrasive desert grit or careless zipping with gloves on
- Three-person rating is optimistic for three full adult kits — plan as a spacious two-person tent with excellent vestibule storage
Bottom line
The Big Agnes Copper Spur HV UL3 is the camping tent I recommend when two hikers want real living space and dual vestibules near 1.5 kg packed — not for hut treks, not for winter alpinism, but excellent for mild three-season wild camps where comfort beats absolute minimum weight.
