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 4/10How much it adds to your pack. This is the whole tent: two people sharing can split it. 4: A bit below average.
Sea to Summit gives a minimum trail weight of 2,018 g (packed 2,069 g), in the 2.0–2.69 kg band. Shared by three that is about 670 g each.
Rain protection
Estimate from maker's specs: flysheet and floor hydrostatic head figures 3/10How well it keeps out heavy, long rain. 3: Below average. Fine for some trips, not others.
Estimate from maker's specs
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 5/10Room to lie, sit up and keep kit inside. 5: Does the job. Average for wild-camping gear.
Sea to Summit's 3.7 m² floor area ÷ 3 people = 1.23 m² each, in the 1.15–1.34 band. Peak height is 123 cm. The inner length is not published.
Packed size
From maker's figures 4/10How much room it takes in your rucksack. 4: A bit below average.
Packs to 50 cm long x 16 cm across: 3.1416 x 8 x 8 x 50 = 10,053 cm³, so 10.05 L, in the 10–14.9 L band.
In short
Good for
- Three backpackers who want a freestanding tent with real headroom (123 cm) and two big doors
- Two people who want a lot of room and gear space for about 2 kg
- Mixed weather where the fly can go up first and a hangout shelter mode helps in showers
Strengths
- Freestanding on one two-hub DAC pole set, with colour-coded pole feet and the fly pitchable first
- Tension Ridge poles give 123 cm peak height, 3.7 m² of floor and two doors with 2 m² of vestibule
- Minimum trail weight 2,018 g, so about 670 g each shared by three
- Apex vent with a closable storm flap, plus baseline vents and a mostly mesh inner for airflow
- New for 2026: recycled, PFAS-free Ultra-Sil LS fly that Sea to Summit says stretches less and dries faster
- Hangout Mode turns the fly into an open shelter on two trekking poles (pole set sold separately)
Weaknesses
- Sea to Summit publishes no fly waterproof rating (two shops list 1,200 mm, which is low), so rain protection is an estimate, not a reviewed score
- Sea to Summit says it is meant for tapered mats: three rectangular mats will not fit
- Packs to 50 x 16 cm (10 L), bigger than lighter 3-person tents
- Brand new for 2026 with no independent test yet, so wind, pitching and durability are unproven
- Sea to Summit rates it 3 season; no mountain or winter rating
