Durston X-Mid 2 vs Big Agnes Copper Spur HV UL2
The two ultralight 2-person tents that come up in every UL forum thread, with very different design philosophies. The X-Mid is a trekking-pole tent that turns gear you already carry into the structure. The Copper Spur is a freestanding tent with its own poles. Both are excellent, they just optimize for different things.
The weights and fabric specs below are checked against the makers’ own pages — Durston Gear documents the X-Mid 2’s offset-pole design, and Big Agnes publishes the Copper Spur’s figures. For a neutral primer on freestanding versus trekking-pole shelters, see REI’s expert-advice library.
Gear research & fact-checking
Quick verdict
Pick the X-Mid 2if you already hike with trekking poles, want the lightest 2-person UL tent under $350, and don't mind a slightly steeper learning curve to pitch correctly.
Pick the Copper Spurif you don't carry trekking poles, want a freestanding design that pitches anywhere (including hard-pack desert and slab rock), and prefer simpler setup at the cost of 14 oz extra.

Open 3-way compareThe fundamental difference: pole philosophy
Almost every other comparison reduces to this one design choice. The X-Mid 2 is non-freestanding — it requires two trekking poles (or an aftermarket pole set) to stand up, and you stake out the corners before raising the structure. The Copper Spur is freestanding — its own hubbed pole system holds the tent up before you stake anything down.
This is not a small thing. It changes how heavy your kit is(X-Mid uses gear you already carry), where you can pitch (Copper Spur sets up on rock slabs and decks where stakes can't penetrate), and how forgiving the tent is in tricky conditions (Copper Spur tolerates a sloppy stake-out; X-Mid does not).
Where the X-Mid 2 wins
Weight — by a lot
14 oz (400 g) lighter trail weight than the Copper Spur — and that's before you account for pole weight. If you already hike with trekking poles, the X-Mid is essentially using gear you're carrying anyway. Net pack weight reduction over the Copper Spur is closer to 1 lb 4 oz once you subtract the Copper Spur's built-in pole weight.
Wind and rain performance
The X-Mid's offset-peak design (one pole tall in front, one pole shorter in back) creates a wind-cutting profile that outperforms most freestanding UL tents. The fly tensions tightly across all four corners and the steep walls shed rain without sagging. Multiple comparison tests put the X-Mid ahead of the Copper Spur in 30+ mph wind.
Peak height — actually noticeable
46 in vs 40 in. Six inches doesn't sound like much, but in practice it means a 6'0" person can fully sit up without hunching at the X-Mid's peak, a position most freestanding UL tents don't allow. Cooking inside the vestibule, changing layers, reading at night all benefit.
$200 cheaper at MSRP
$300 vs $499. Even adding Durston's aluminum pole set ($40) for non-trekking-pole users brings the X-Mid to $340 — still $159 below the Copper Spur. The cost-per-gram of UL tent material at the X-Mid's price point is almost unmatched.
Heavier fabrics, tougher tent
Counter-intuitive but true: the lighter X-Mid actually uses heavier-denier fabrics than the Copper Spur (20D vs 15D fly, 20D vs 15D floor). The weight savings come from the pole system, not thinner materials. Net result: the X-Mid is actually more abrasion-resistant on the floor and more resistant to pinhole leaks long-term.
Where the Copper Spur wins
Pitch flexibility — anywhere is fair game
Freestanding means you can pitch on solid rock, decks, gravel pads, established platforms — anywhere stakes won't bite or aren't allowed. The X-Mid requires 4 stakes minimum. In Sierra alpine bowls or Northeast slab rock, the Copper Spur is the right call.
Setup is dead simple
Clip the inner to a hubbed pole, throw the fly on, stake the corners. 3 minutes of muscle memory once practiced. The X-Mid requires staking out a perfect rectangle FIRST, then raising the poles, and the rectangle has to be correct or the pitch drum-tight tension is wrong. First 5 X-Mid pitches are noticeably harder.
Better for non-trekking-pole hikers
If you don't already use trekking poles, you have to buy Durston's aluminum pole set ($40) or factor poles into the buying decision. The Copper Spur ships ready to pitch with no other gear required, a real consideration for day-pack weekenders who don't use poles.
Wider name recognition
Big Agnes is at REI, Backcountry, dozens of local outfitters. Durston is online-only direct-from-manufacturer with shipping lead times that occasionally stretch (especially when new inventory drops). For a tent you can hold in your hands pre-purchase, the Copper Spur wins.
Real-world differences (after a season of use)
Field-test observations after multiple trips with each:
Pitch time
X-Mid: 5 min first try, ~3 min after 5+ pitches. Copper Spur: 3 min first try, ~3 min always. The X-Mid's skill curve evens out fast but starts steeper.
Condensation
X-Mid: significantly less. The double-wall design with a large fly-to-inner gap and full-height venting wins this category. Copper Spur: morning wipe-down often required.
Pack volume
X-Mid: 5" × 17" (no poles in the bag). Copper Spur: 6" × 19.5". The X-Mid's smaller pack footprint means more room for food and bear-canister fits.
Resale
Copper Spur holds 50–60% of MSRP at 2 years on r/ULgeartrade. X-Mid holds 75–85% — partly because Durston rarely discounts new units, and partly because demand outstrips supply during peak ordering windows.
Who should buy which
Buy the X-Mid 2 if you...
- · Already hike with trekking poles
- · Are doing a thru-hike or 7+ day trips where weight compounds
- · Want the best $/g value in the UL tent market
- · Can pitch on dirt or grass (not always rock or platforms)
- · Don't mind a 3–4 trip learning curve
Buy the Copper Spur if you...
- · Don't use trekking poles regularly
- · Pitch in places without good stake purchase (slab rock, hard pack, sand, decks)
- · Want a freestanding tent for the "move it after pitching" flexibility
- · Prefer a brand you can buy at REI or local outfitters
- · Are a less-experienced backpacker who values simple setup
Frequently asked questions
Which is lighter. Durston X-Mid 2 or Copper Spur HV UL2?
The Durston X-Mid 2 is lighter at 1 lb 12 oz (794 g) trail weight vs the Copper Spur's 2 lb 10 oz (1,190 g), a 14 oz (400 g) advantage. The X-Mid achieves this by using your trekking poles instead of carrying dedicated tent poles. If you already use trekking poles, this is essentially free weight savings.
Do I need trekking poles for the Durston X-Mid 2?
Yes, the X-Mid 2 is a non-freestanding design that requires two trekking poles to pitch (or you can buy Durston's optional aluminum pole set for around $40). If you don't hike with trekking poles already, factor that into the cost calculation. The Copper Spur is freestanding and includes its own DAC poles.
Which handles weather better?
The X-Mid 2's offset peak design and steep walls shed wind and rain remarkably well — better than most freestanding UL tents in moderate-to-strong wind. The Copper Spur is comparable in mild rain but the steeper, more vertical walls of the X-Mid handle gusts that would deform a Copper Spur. In condensation-heavy still-air conditions, the X-Mid's larger fly-to-inner gap also wins for ventilation.
Which is harder to pitch?
The Copper Spur is significantly easier for first-time users — clip the inner to a hubbed pole, throw the fly over, you're done. The X-Mid 2 has a steeper learning curve: you stake out 4 corners first (so the rectangle has to be square), then raise the trekking poles. Once practiced, it's about the same time as the Copper Spur, but the first 5 pitches are noticeably harder.
How does pricing compare?
The X-Mid 2 is $300 vs the Copper Spur's $499, a $200 difference at MSRP. Add Durston's optional aluminum poles ($40) if you don't hike with trekking poles, bringing total to $340. Even with the optional poles, the X-Mid is $159 cheaper than the Copper Spur. Durston rarely discounts; Big Agnes runs 20–30% off seasonally.
Which is better for thru-hikers?
The X-Mid 2 is the favorite among thru-hikers — it's lighter, cheaper, more weather-capable, and uses poles you're already carrying. The Copper Spur is more popular with weekend backpackers who occasionally do longer trips. Among current PCT/CDT thru-hikers, the X-Mid (in its various sizes) outsells freestanding UL tents nearly 3:1 according to recent gear lists analyzed at trail association forums.
