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.
Sierra Designs' minimum weight is 930 g, under the 1.0 kg line. Ultralight Outdoor Gear weighed the flysheet and inner at 898 g without pegs and bags, and one owner's video gives 978 g with pegs. Reviewers who weighed the whole kit with stuff sacks got 1,010 g (The Great Outdoors) and 1,080 g (Advnture and Live for the Outdoors), which would be the 1.0–1.49 kg band. Trekking poles are not included.
Rain protection
From maker's figures 8/10How well it keeps out heavy, long rain. 8: Clearly better than most.
Flysheet and groundsheet are both 3,000 mm, in the 3,000 mm+ band, and the floor is over 2,000 mm so no point comes off. Alpinetrek lists the flysheet at 1,200 mm, but that is the US High Route's figure: Sierra Designs' own sheet and three reviewers give 3,000 mm for this European version. The printed figure alone gives 8 at most: a 9 or 10 needs 3 reviews that say it stays dry in real storms.
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 8/10Room to lie, sit up and keep kit inside. 8: Clearly better than most.
Sierra Designs gives the inner ('nest') floor as 1.54 m², for one person: in the 1.35–1.59 m² band. The 259 x 107 cm figure that some reviewers call the inner size is the tarp (fly-only) footprint: 2.59 x 1.07 m = 2.77 m², matching Sierra's 2.76 m² tarp area. We found no published inner length. Headroom is 114 cm in tarp mode and 102 cm with the inner (Live for the Outdoors).
Packed size
From maker's figures 6/10How much room it takes in your rucksack. 6: A bit better than average.
Sierra Designs gives a packed size of 40 x 16 cm (a stuff-sack cylinder): 3.1416 x 8 x 8 x 40 = 8,042 cm³, so 8.0 L, in the 7–9.9 L band. It is about the size of a one-litre bottle.
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 5/10How quickly and easily one person can pitch it, including in wind and rain.
3 reviews on pitching, e.g. "A little practice is required to set it up but once you get the hang of it it’s easy.".
Condensation*
Estimate: only 1 review about condensation (fewer than the 3 we need, so never above 8) 8/10How dry it stays inside on still, damp nights; higher is drier.
1 review on condensation, e.g. "On test, condensation was minimal and never an issue that transferred to the inner or to your sleeping bag.".
In short
Good for
- Solo three-season backpacking and long-distance walking for people who already carry trekking poles
- Wild camps where you want a tent that doubles as a tarp on dry nights (the fly alone weighs about 0.48 kg)
- Taller walkers who want headroom without carrying a pole set
Strengths
- Light at about 0.9 to 1.1 kg with no poles to carry, and packs to roughly the size of a one-litre bottle (40 x 16 cm)
- Good headroom for a trekking-pole tent: 114 cm in tarp mode and 102 cm with the inner clipped in
- Fly and floor are both 3,000 mm, a big step up from the US version's 1,200 mm
- Three ways to pitch it: fly and inner together, fly alone as a tarp, or inner alone as a bug shelter
- Two small vestibules (0.7 m² each) and a strutted door vent that kept condensation low in testing
Weaknesses
- Trekking poles are not included, and one owner set his at about 125 cm, so with poles his kit came to about 1.4 kg
- Tricky to pitch the first time: Matt Jones advises a practice pitch at home, and it needs ground that holds pegs or the fly goes slack and noisy
- Large flat side panels can flap in strong wind; the reviewers rate it for moderate wind, so it is not an exposed-ridge or winter tent
- Small porches with no room to cook, and only one small mesh pocket inside
- Heavier in real use than the 930 g Sierra Designs figure: 1,010 g with stuff sacks at The Great Outdoors and 1,080 g at Advnture and Live for the Outdoors
- No published inner length, and wind stability and durability are estimates, not reviewed scores for lack of evidence
