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 1/10How much it adds to your pack. This is the whole tent: two people sharing can split it. 1: A real weak point.
OEX lists 5 kg (GO Outdoors, Millets and Blacks share the same copy), in the 2.7 kg+ band. The tent ships in a split bag so three people can share it.
Rain protection
From maker's figures 8/10How well it keeps out heavy, long rain. 8: Clearly better than most.
OEX's copy has one fabric line for the fly and the groundsheet together: 'Fly/inner groundsheet: 20D SilNylon/PU ripstop - 3000HH' (the same text on GO Outdoors, Millets and Blacks, with no separate groundsheet line). It names both parts and gives one figure, so we band 3,000 mm for both: the fly is in the 3,000 mm+ band and the groundsheet is over 2,000 mm, so no point comes off. 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) 7/10How steady it stays in strong wind on open ground. 7: Better than most.
No published review says how it copes with wind, so this is an estimate from the maker's season rating.
Space
Estimate from maker's specs: berths and tent shape (no floor area published) 5/10Room to lie, sit up and keep kit inside. 5: Does the job. Average for wild-camping gear.
Estimate from maker's specs
Packed size
From maker's figures 1/10How much room it takes in your rucksack. 1: A real weak point.
OEX's pack size is 50 x 30 x 15 cm, a box of 50 x 30 x 15 = 22,500 cm³, so 22.5 L, in the 15 L+ band.
In short
Good for
- Three people who want a four-season geodesic tent for winter and high-ground camps and can split the 5 kg between them
- Campers who want a snow skirt and room to cook inside in bad weather
- Groups sharing one tent in the hills
Strengths
- Fully geodesic dome with an adjustable snow skirt that folds away (OEX)
- Fly and groundsheet 3,000 mm HH
- Split bag so the weight can be shared
- Internal dry lines, storage pockets and a roof loft
Weaknesses
- Heavy at 5 kg and packs to 50 x 30 x 15 cm, about 22.5 L
- OEX publishes no floor area, so space is an estimate, not a reviewed score
- No independent review found, so wind, pitching and durability are estimates, not reviewed scores: the four-season and storm claims are OEX's own
- Wind is an estimate from the maker's season rating until 3 reviews cover it, and the winter score rests on that estimate
- OEX's copy gives one 3,000 mm HH figure for fly and groundsheet together
- OEX is GO Outdoors' house brand, so it is sold only through that group (GO Outdoors, Millets, Blacks)
