Seams sealed with heat-sealed strips. Room in 15 deniers polyamide breathable and water-repellent, partly made of mosquito net, to avoid contact with condensation drops.
Wind resistance
We test all our tents in a wind tunnel on a rotating platform 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.
Ventilation and condensation prevention
Bedroom with mosquito net sections for ventilation and sections in a water repellent fabric to protect from condensation and draughts. Two high ventilations and a two-way zip on the door to optimise air flow. To reduce condensation inside your tent, it must be properly assembled, with the fabric kept taut without over-stretching. The ventilation and air flow reduces humidity inside your tent.
Sun protection
The flysheet fabric filters UV rays with a UPF of 30. Please note: a large amount of UV rays can pass through an open door. Protect your skin.
Entire tent made of 20% recycled materials, thereby reducing the product's environmental impact. Flysheet made up of 50% recycled materials. The bedroom is made of a "bulk dyed" component that reduces the amount of water used. The tent poles are coloured using an innovative anodising process that does not use nitric and phosphoric acids.
Every tent sold at Decathlon is guaranteed for 2 years of normal use (your receipt or loyalty card is used as proof of purchase). In case of any problem, get your tent examined at your local Decathlon store. All Forclaz tents are repairable: spare parts and tent pole repair services are available in the workshop of your Decathlon store, on the shopfloor or at decathlon. fr
A score for comparing products' environmental impact
The environmental impact of the products is calculated based on the life cycle of the product and with different indicators. A score ranging from A to E is attributed so that you can easily identify the products with a better environmental performance compared to products of the same type (T-shirts, trousers, backpacks,...). Decathlon totally backs the environmental labelling approach. For more info: http:..sustainability.decathlon.com.

Product test
The waterproofing of Forclaz tents is validated by testing that a pitched tent placed under a 200 litre/m²/hr shower (tropical rain) for 4 hours prevents water from passing through the seams, flaps, openings, zips, etc. The water column test (= mm schmerbers) measures the waterproof rating of the fabric. Wind resistance: tents are set up in a wind tunnel on a rotating platform to expose each side of the tent to the wind. We also carry out numerous field tests in real-life conditions.

Stockage tips
Storage: after use or cleaning, wait until the tent is perfectly dry before putting it away in order to avoid bad smells and mould.
