Structure, poles and pegs

Lightweight, shock and frost resistant aluminium pole: 7001 T6 Yunan SD70PF Ø 8.3 mm aluminium.
Optimised square tent pegs: “anvil” head, oversized main part, extremely resistant and lightweight (7075 T6 aluminium). Non-anodised for a lower environmental impact.
Simple Y-shaped dome: the main pole splits into 3 feet giving a semi-freestanding structure. Top pole provides volume and therefore capacity.


Separate flysheet and bedroom. Traditional pitching method: bedroom on the ground and clipped to the poles. Cover the whole tent with the flysheet. Adjust the tautness.
If needed, the bedroom can be dismantled from inside.
Intuitive pitching thanks to colour coding on the pole, bedroom and flysheet.
When it rains, to pitch the flysheet first, you will need the compatible groundsheet (ref 8545723).


Forclaz tents are laboratory-tested: pitched tent, 200 litres/sqm/hour (4 hours, equivalent to a tropical storm). They are also tested in the field by a sample user group.
20 denier polyester (PES) flysheet and 40D polyamide (PA) groundsheet have a polyurethane coating (inside) and silicone (exterior).
Seams sealed with thermo-bonded strips.
Multi-component bedroom combining breathability, wind protection and prevents 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 guarantee 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 60 km/h, measured near ground level.
Our tents are certified by the CSTB independent laboratory in Nantes.

Ventilation and condensation prevention

Bedroom with mosquito net sections for ventilation and water-repellent fabric sections to protect from condensation and draughts. There are 2 large top ventilation areas that you can close using a Velcro strip.
To limit condensation inside the tent, it must be correctly assembled, canvas taut, but not excessively so. Two-way zips on the door to keep it open. The use of ventilation and good air circulation limits humidity inside your tent


3 seasons tent: your tent will protect you from difficult weather conditions that you may encounter in spring, summer or autumn. The tent will withstand light snowfall but is not designed for heavy loads that would weigh on its structure.
When it snows, shake your tent regularly to make the snow fall to the ground and avoid too much weight being supported by your tent’s structure.

Eco-designed tent:

The poles are coloured using an innovative anodising method which eliminates the use of nitric and phosphoric acids.
Non-anodised tent pegs:
Your tent pegs may have a “rough” or “used” appearance but they still have all their technical and resistant features; not coloured or anodised (no acid is used since this only has an aesthetic effect).
These factors help to limit the environmental impact of your product.

Repair and after-sales service

As designers and users who love our field, we care 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, on the website or at the address
If you have a problem, don't hesitate to have your tent looked at in your local Decathlon store.

Test Product Waterproof testing of Forclaz tents take place with the tent assembled, under 200 litres of water/sqm/hour (tropical rain) for 4 hours, excluding water entering through seams, flaps, openings, zips, etc. The water column test (=mm Schmerbers) measure the fabric’s waterproofness. We test all our tents in a wind tunnel on a turntable on all 4 sides. We also test the parts (abrasion, tearing, split, etc.).
