Our ratings (out of 10)
1 to 10, compared with the whole market. Each says what it's based on. How we score
Weight
From maker's figures 9/10How much it adds to your pack. This is the whole tent: two people sharing can split it. 9: Among the best you can buy for this.
Big Agnes lists a trail weight of 859 g (tent, fly and poles, no pegs), under 1.0 kg; packed with 11 pegs and bags it is 1.01 kg. Ultralight Outdoor Gear weighs the parts at 886 g without pegs and bags, the same band.
Rain protection
From maker's figures 3/10How well it keeps out heavy, long rain. 3: Below average. Fine for some trips, not others.
Fly 1,500 mm is the 1,500–1,999 band, band 3 (5 out of 10), then one band lower because the floor is only 1,500 mm, under 2,000 mm.
Wind
Estimate from maker's specs: maker's season rating (fewer than 3 reviews about wind) 5/10How steady it stays in strong wind on open ground. 5: Does the job. Average for wild-camping gear.
No published review says how it copes with wind, so this is an estimate from the maker's season rating.
Space
From maker's figures 6/10Room to lie, sit up and keep kit inside. 6: A bit better than average.
Big Agnes's 2.6 m² floor (218 cm long, 132 cm wide at the head tapering to 107 cm) ÷ 2 people = 1.3 m² each, in the 1.15–1.34 band; the floor tapers, so two wide mats are tight.
Packed size
From maker's figures 5/10How much room it takes in your rucksack. 5: Does the job. Average for wild-camping gear.
Packs to 49 cm long x 16 cm across: 3.1416 x 8 x 8 x 49 = 9,852 cm³, so 9.85 L, in the 7–9.9 L band (Ultralight Outdoor Gear lists 50 x 15 cm, 8.8 L, same band).
In short
Good for
- Solo walkers, or two light-sleeping friends, who want one of the lightest double-skin tents
- Summer and mild spring or autumn wild camps where pack weight and packed size come first
- Pitching on soft ground, since the rear corners need pegs
Strengths
- Trail weight of 859 g, so two people sharing carry about 430 g each
- Fast-fly option: the fly pitches over the footprint (sold separately) without the inner, for 676 g
- Semi-freestanding hub pole with a high roof (107 cm at the head)
- Single door with a 0.7 m² vestibule
- Recycled 15D nylon fabric treated without PFAS
Weaknesses
- Low waterproof ratings: fly and floor are both 1,500 mm, so a footprint is advisable on wet ground
- Tight for two: 1.3 m² each and the floor tapers to 107 cm at the foot end
- One door and a small vestibule (0.7 m²) for two people's kit
- Not fully freestanding: the rear corners need pegs, which is hard on rock
- No independent review of this HyperBead version yet, so wind, pitching and durability are estimates, not reviewed scores; ultralight 15D fabric is thin, so handle it with care
- The footprint is an extra purchase
