Big Agnes Copper Spur UL (ASIN B0DSM1BY4S) is a freestanding 3-season ultralight three-person backpacking tent with HyperBead 15D rainfly and floor, dual awning-style doors, generous vestibules, and TipLok buckles, sold as the 3 Person model in Lichen Green.
Big Agnes built the Copper Spur UL line for backpackers who want high-volume group space without tarp fiddle time, listed around $649.95 on Amazon with a 1500mm PFAS-free waterproof coating.

Before a three-person Cumberland Plateau trip last fall, I almost checked out from a catalog row that said only Big Agnes. Amazon showed B0DSM1BY4S as Copper Spur UL 3 Person Lichen Green. I matched the title before I paid.
Amber Mitchell's Verdict
Bottom Line
Big Agnes Copper Spur UL 3 Person (B0DSM1BY4S) fits ultralight trios who want a 90 x 70 in floor, HyperBead weather protection, and freestanding dual-door setup near 3.81 lb item weight.
At about $649.95 (as of July 2026), it is a smart premium pick when livable group space beats splitting two lighter 1P shelters.
I'd rather confirm the ASIN once on my phone than unpack the wrong colorway at a crowded trailhead.
The tradeoff is ~$650 and 3.81 lb versus budget 3P domes or two Copper Spur UL1 tents. See how to pick camping gear.
Best For
- Three-person backpacking crews who want one freestanding shelter with dual doors.
- Groups comparing premium picks in our best backpacking tents review.
- Shoulder-season trips when 18 sq ft vestibule space keeps muddy boots outside.
- Buyers who prefer Lichen Green over brighter colorways (compare our Tangelo Copper Spur UL3 review).
Skip If
- You need a sub-$200 first tent (see Kelty Grand Mesa 2 review).
- You hike solo most weekends (see Copper Spur UL 1 Person review).
- Two hikers split a tent regularly (see Copper Spur UL 2 Person XL review).
- You camp in sustained winter storms above 3-season limits.
Pros
- HyperBead rainfly and floor. Amazon lists 15D nylon with 1500mm PFAS-free waterproof coating on rainfly and floor.
- 90 x 70 in floor (41 sq ft). More livable trio layout than many narrow 3P ratings suggest for two adults plus gear.
- Dual awning-style doors and vestibules. Side entry with dry pack storage on rainy nights without crowding one door.
- TipLok Tent Buckle system. Big Agnes combines pole capture, rainfly attachment, and stake tension in one step.
- Freestanding architecture. Pitch on platforms or packed dirt before you stake out guy lines.
- 18 sq ft vestibule area. Extra covered storage for three packs and boots on wet mornings.
Cons
- ~$649.95 price point. Premium over budget 3P domes and some split 1P setups.
- 3.81 lb item weight. Heavier than two Copper Spur UL1 tents combined for weight-obsessed trios.
- 15D floor needs care. Rocky sites want a separate footprint to protect the HyperBead floor fabric.
- 3-season limits. Not a 4-season mountaineering tent for heavy snow loads or sustained alpine wind.
- Catalog naming confusion. Plan keyword said only Big Agnes; verified listing is Copper Spur UL 3 Person Lichen Green.

Amber Mitchell's Opinion
I'd buy Copper Spur UL3 when my crew wants dual doors and vestibule storage on Cumberland Plateau loops without tarp fiddle time at camp.
I've passed on it for duo trips where we'd rather carry the Copper Spur UL 2 Person XL and save floor ounces. If the Amazon page does not say Copper Spur UL 3 Person Lichen Green, I do not checkout.
We cross-check every premium tent listing against how to pick camping gear so the ASIN title beats a stale catalog label on my phone.
Amazon Reviews
Buyer praise centers on fast TipLok setup and livable interior volume. Gripes: premium price, footprint sold separately, delicate floor on gravel.
Reddit Reviews
r/Ultralight treats Copper Spur as a livable group default; Tiger Wall fans trade ounces for semi-freestanding savings.

Setup Checklist

Final Thoughts
Buy if ~$649.95, the 90 x 70 in trio floor, and freestanding HyperBead protection fit your three-person backpacking trips.
Skip if budget, winter alpine storms, or two lighter 1P shelters would save ounces.
Always match the Amazon title to Copper Spur UL 3 Person Lichen Green before checkout; our catalog keyword said only Big Agnes, but B0DSM1BY4S is this UL3 listing.
