Component waterproofing
This garment has been subjected to a shower test using 60 litres of water/sqm/hour for 2 hours. This test reproduces the average conditions of a rain shower in the mountains.
A waterproof rating of 5,000mm means the fabric can withstand pressure exerted by 5,000mm of water (the equivalent of a rain shower lasting for two hours).
Waterproofing is expressed in Schmerbers (for example: 5,000 Schmerbers).
Component breathability
To assess the breathability of the fabric, the evaporative resistance, RET (test based on the ISO 11092 standard), is measured. The lower the fabric's resistance, the more water vapour generated by physical activity evaporates, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 920 = little or no breathability.
Component durability
We conduct numerous laboratory tests to validate the highest standards in terms of durability: a resistance test to abrasion and friction to ensure that the fleece does not pill, a colour fastness test to check the behaviour and resistance of the colours and an ageing test to check that repeated washing does not alter the properties of the fabric, its behaviour, its thickness or its appearance.
