Dimensions and habitability
Room length 215 cm
Width 230 cm at head and 210 cm at feet
Room height 122 cm at highest
The very large apse (storage / living area in front of the room) is 205 cm deep and 240 cm wide, i.e. almost 5 m², so that 4 people can sit together or store their gear under cover (backpacks, shoes, bicycles, etc.).
7 pockets in the room. Clothesline loops.
Architecture, hoops and sardines
The 3 poles form a non-self-supporting tunnel. This structure makes for a lightweight tent that is strong and quick to erect, but needs to be secured to the ground to stay in place
Aluminum poles 7001 Ø 10.2 mm.
The head of the 7075 T6 aluminum sardines is shaped like an anvil, making them very strong. 10 g / sardine. They are non-anodized for limited environmental impact.
Assembly / disassembly
Quick to set up.
As the double-roof and sleeping chamber are pre-assembled, simply slide the poles into the sleeves on the double-roof and tension them.
Dismantling is just as quick.
To store the tent in its cover, simply fold the tent onto itself to approximately the width of the cover, fold the poles into a bundle and place them on the sleeping chamber or double-roof, then roll the whole assembly compactly to slide them into the cover.
Waterproofing
Forclaz tents are laboratory-tested: tent erected, 200 liters/m²/hour (3 hours, equivalent to a tropical downpour). They are also field-tested by a panel of users.
20-denier polyester (PES) rainfly and 40D polyamide (PA) ground sheet are made of coated polyurethane (inside) & silicone (outside).
Seams sealed with heat-sealed tape.
Multi-component chamber combining breathability, wind protection and condensation control.
Wind resistance
We test all our tents in wind tunnels, in a wind tunnel on a turntable, to expose each side of the tent to the wind.
To guarantee wind resistance, the tent must be properly erected, stretched without excess, with all guy wires properly deployed around the tent. This will ensure that the tent remains habitable even when the wind speed is measured at 70 km/h close to the ground.
Our tents are certified by the independent CSTB laboratory in Nantes.
Ventilation and condensation control
Mosquito netting for ventilation and water-repellent fabric to protect against condensation and draughts. There is ample ventilation at the front of the tent, as well as ventilation at the feet.
To limit condensation inside the tent, it must be correctly pitched, with the canvas stretched taut, but not excessively so. Ventilation and good air circulation limit humidity inside the tent.
The back of the fly can be raised for even better ventilation.
Seasons
3-season tent: your tent will protect you from the harsh weather conditions you may encounter in spring, summer or autumn. It will withstand small snowfalls, but is not designed to withstand heavy loads on the structure.
In the event of snow, remember to shake your tent regularly to remove any accumulated snow from the ground, and to avoid putting too much weight on the tent structure.
Repairability and after-sales service
As designers, we are concerned about the durability of our products, which is why all our tents are designed to be repairable.
For this model, you will find the following spare parts:
- the rain fly (ref 8739746)
- the inner chamber (ref 8739740)
- the poles (ref 8739748)

Resistance
Your tent is designed for touring bivouacs, not for static daily use.
We advise you to avoid leaving your tent in direct sunlight as much as possible, as ultra-light fabrics can be sensitive to UV rays, which can weaken them.
Warranty
5 years. All our tents are repairable. Information in store or on decathlon.fr
