The waterproof rating of the Forclaz tents is validated by placing a pitched tent under 200 L/sqm/h shower of water (tropical rain) for 4 hours, and checking that no water passes through the seams, flaps, openings, zips, etc.
The water column test (= mm Schmerber) measures the waterproof rating of the fabric.
We test all our tents in a wind tunnel, on a rotating table to check all 4 sides.
We also perform tests on the components (abrasion, tearing, perforation, etc.)
This tent has been tested and validated in the field in real-life conditions. It was used for 5 weeks by several people who went trekking in the Canary Islands for 2 weeks, followed by 3 weeks on the GR10 route in the Pyrenees.
It has also been tested on Canadian trails by 2 of our partners.
