Length of the room 220 cm Width 180 cm Inside height 119 cm (at the highest point) Total height of the tent 128 cm Two 60 cm deep side porches (storage space between the bedroom and the flysheet) that can accommodate the backpacks (from 50 to 70 L) of three occupants, mountain equipment and hiking boots. 3 pockets in bedroom. 1 inner hook at the top for hanging a lamp and an adjustable horizontal clothes line.
Architecture, tent poles and tent pegs
7001 aluminium poles. Ø 9.5 mm dome, top tent pole Ø 10.5 mm. Durable lightweight aluminium. Tent pegs/stakes: Length 17 cm, Ø 6.1 mm. Non-anodised 7075 aluminium for maximum strength and lightness while lowering the environmental impact. Traditional dome shape that makes the structure free-standing and gives it good durability. Top pole provides volume and therefore capacity.
Extremely quick pitching/striking. The flysheet and bedroom are pre-assembled. You then need to insert the tent pole in the sleeves of the flysheet (colour code). It is also quick to strike. To store the tent in its bag, just fold up the tent until it is as wide as the bag, fold up the tent poles into a bundle and place them on the bedroom or the flysheet, and roll everything up into a small bundle to fit it all in the bag.
Forclaz tents are laboratory-tested: pitched tent, 200 litres/sqm/hour (3 hours, equivalent to a tropical storm). They are also tested in the field by a sample user group. 75 denier polyester flysheet, polyurethane-coated (interior) water-repellent treatment (exterior), P75D groundsheet in the bedroom. Seams taped with heat-sealed strips. Multi-component bedroom (P66D) that is breathable, provides protection from the wind and reduces condensation.
Wind resistance
We test all our tents in a wind tunnel on a turntable where we can expose each side of the tent to the wind. To test its wind resistance, the tent must be properly pitched, taut but not stretched, with all the guy ropes in position around the tent. It should remain habitable at wind speeds of 70km/h, measured near ground level. Our tents are certified by the CSTB independent laboratory in Nantes.
Ventilation and condensation prevention
Bedroom with mosquito screen for ventilation and water-repellent fabric to protect from condensation and draughts. Large vent at front of tent and additional vent at feet end. To reduce condensation inside your tent, it must be properly pitched, with the fabric kept taut without being over-stretched. Vents and good air flow will help reduce humidity inside your tent.
3-season tent: your tent will protect you from the harsh weather conditions you can encounter in the spring, summer or autumn. It will withstand light snowfall but is not designed to withstand heavy loads that would weigh on the structure. In case of snow, remember to shake your tent regularly in order to bring down any snow that has accumulated to avoid putting too much weight on the structure of your tent.
Environmental approach
Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this impact on the environment, we have chosen a dyeing method called “two-tone” for the grey fabrics of the bedroom and the double canopy, which consists of dyeing only one thread out of two. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards.This process reduces the CO2 emissions of this product.
The stakes are not coloured because they are not anodised (no acid used). They may have an unfinished or used appearance but retain all their technical characteristics. These actions help to reduce the environmental impact of your product.
Repairs 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. You will find the detachable parts (poles, bedroom, etc.) in store or in the workshop of your local Decathlon, or on the website. If you have a problem, don't hesitate to have your tent looked at in your local Decathlon store. Repair kit (ferule, patch): 20 g
Your tent is designed for itinerant bivouacking, it is therefore not designed for static use in the sun. We recommend that you avoid leaving it in the sun as the ultra-light fabrics can be sensitive to UV light, that damages them.
