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.
Nemo's minimum weight of 822 g is under the 1.0 kg band (1.02 kg packed).
Rain protection
From maker's figures 1/10How well it keeps out heavy, long rain. 1: A real weak point.
Fly 1,200 mm is the 1,200–1,499 band, band 2 (3 out of 10), then one band lower because the floor is only 1,500 mm, under 2,000 mm. Nemo's OSMO fabric is made not to sag when wet, but this is the fabric's rating only.
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 10/10Room to lie, sit up and keep kit inside. 10: The best you can buy for this.
Nemo's 1.9 m² floor for one person is in the 1.6 m²+ band (floor 220 cm long, 99 to 75 cm wide, peak height 98 cm).
Packed size
From maker's figures 8/10How much room it takes in your rucksack. 8: Clearly better than most.
Packs to 32 x 19 x 7 cm = 4,256 cm³, so 4.26 L, in the 4–6.9 L band.
What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Pitching*
Reviewers' average 9/10How quickly and easily one person can pitch it, including in wind and rain.
3 reviews on pitching, e.g. "The single 3-arm hubbed pole system means setup was intuitive even when I was tired".
Condensation*
Estimate: only 2 reviews about condensation (fewer than the 3 we need, so never above 8) 7/10How dry it stays inside on still, damp nights; higher is drier.
2 reviews on condensation, e.g. "One morning revealed quite a lot of condensation on this section".
In short
Good for
- One person who wants a very light tent with room to sit up
- Three-season backpacking and wild camps in mild or sheltered weather
- Walkers who put weight and pack size first and can use a footprint for wet ground
Strengths
- 822 g minimum weight and 1.02 kg packed
- 1.9 m² floor and a 98 cm peak height, roomy for one
- Single hubbed pole with a Flybar clip to add headroom; semi-freestanding, but the foot corners need pegging (Lotsa Fresh Air)
- Packs to 32 x 19 x 7 cm in a square stuff sack that sits flat in a rucksack
- PFAS-free OSMO fabric that Nemo says does not sag when wet
Weaknesses
- Low waterproof figures: fly 1,200 mm, floor 1,500 mm; Lotsa Fresh Air called the floor low next to rivals, and Nemo's 2,000 mm footprint adds weight
- One door and one small vestibule (0.7 m²), tight for cooking or a big rucksack (Lotsa Fresh Air)
- Single-wall headroom section caused condensation one morning (Lotsa Fresh Air)
- Wind, pitching and durability are estimates, not reviewed scores: fewer than 3 hands-on tests of the 1P were found
