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 5/10How much it adds to your pack. This is the whole tent: two people sharing can split it. 5: Does the job. Average for wild-camping gear.
Decathlon's parts list gives flysheet 860 g + bedroom 540 g + pole kit 410 g = 1,810 g, in the 1.5–1.99 kg band; the method bands the minimum trail weight. Its headline 2.08 kg also includes 14 pegs (145 g), guylines, bags and a repair kit and would be the 2.0–2.69 kg band, band 2 (3 out of 10).
Rain protection
From maker's figures 7/10How well it keeps out heavy, long rain. 7: Better than most.
Flysheet over 2,000 mm is the 2,000–2,999 mm band (banded at 2,000 mm); the floor is over 3,000 mm, so no point is taken off.
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.
Decathlon gives a 210 cm bedroom, 130 cm wide at the head and 105 cm at the feet (its floor plan; the 115 cm on the plan is the porch depth): 210 x 117.5 (average width) = about 2.47 m², or 1.23 m² each for two, in the 1.15–1.34 band. Decathlon's '60 cm per person' gives 1.26 m² each, the same band. Bedroom height is 93–95 cm.
Packed size
From maker's figures 3/10How much room it takes in your rucksack. 3: Below average. Fine for some trips, not others.
Decathlon states a 13.6 L bag (42 x 18 x 18 cm), in the 10–14.9 L band.
In short
Good for
- Two walkers who want a tunnel tent with a very large porch (1.9 m²) for cooking and kit
- Trips where the tent can be pegged out, since it will not stand up on its own
- Walkers who value a 5-year warranty and Decathlon's spare parts
Strengths
- Tent body, fly and poles weigh 1.81 kg; the whole kit with pegs and bags is 2.08 kg
- Porch of 1.9 m², with a vent in the porch and one in the bedroom
- Inner and fly come pre-attached; the inner door has a mesh layer and a fabric layer, so you choose ventilation or warmth
- Fly over 2,000 mm and floor over 3,000 mm; a 5-year warranty
- Clothesline, two hooks and four pockets inside; the awning folds back for a view out
- Decathlon sells a ground sheet that also lets you pitch the fly alone as a tarp
Weaknesses
- The biggest pack of the MT900 tents Decathlon sells for two: 13.6 L (42 x 18 x 18 cm)
- Not freestanding: needs pegs and guylines, so it is hard to pitch on rock
- One door only, and the bedroom narrows to 105 cm at the feet
- No independent review yet and one Decathlon customer review, so wind, pitching and durability are estimates, not reviewed scores
- Decathlon says the ultralight fabrics should not be left in strong sun
