Product's waterproofing
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.
Fabric waterproofing
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.
Fabric breathability
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 = breathable fabric - RET > 12 = slightly or not breathable fabric. If pants have a RET between 9<RET<12
Product's breathability
In addition to the main fabric's breathability, these trousers have been designed with two side zips, enabling air flow for temperature regulation and improved ventilation.
Full length two-way zip
This new generation 2-way zip offers the same waterproofing as a classic silicone zip (similar to those on pockets) while being more flexible, which improves the overtrousers compression when packed away. Plus, this zip is easier to handle, which helps to make it longer lasting. The 2-way zip and full length opening, allow you to fit or remove trousers, crampons, skis, which is an added bonus during a storm.

    Winter trousers

    Good fit and sturdy with reinforcement sections. Full length zips are very useful. These are definitely a winter product, they become a bit sweaty in warmer climates
