The overtrousers have been approved in a shower test under 100 litres of water / sqm / hour during 3 hours. This test reproduces the conditions of a heavy mountain downpour.

We measure a fabric's resistance to a water column, in mm (based on the ISO 811 standard). The higher the water pressure resistance, the more waterproof the fabric. Components 2000 mm waterproofing, resists up to 2000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours).
With waterproofing greater than 30,000 mm, the Alpinism overtrousers offer an extremely high level of waterproofing.

To find out whether a fabric is breathable, we test its evaporate resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more moisture, generated by an active body, is evaporated, and therefore the higher the fabric's breathability.
We consider that if:

- RET < 9 = highly breathable fabric
- 9 - RET > 12 = slightly or not breathable fabric.
If pants have a RET between 9
