The resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the JIS 1092 standard).The higher the water pressure, the more waterproof the fabric. This garment has been validated in a shower test under 60 L of water/sqm/hour for 1h.This test reproduces the average conditions of a rain shower in the mountains.
A component with a 5,000mm rating withstands the pressure of a 5,000mm column of water (equivalent to a 1h rain shower)

Component breathability is measured by its thermal evaporative resistance (RET).
This is its capacity to let water vapour generated by the body during physical activity escape and therefore avoid water accumulating on the skin.
The lower the RET, the more breathable the fabric.
RET ≤ 6: very breathable fabric
RET ≤ 12: breathable fabric
RET ≤ 20: little breathability

Our product has a 12 RET rating

Created in our international design centre at the foot of Mont Blanc in France, these trousers are then manufactured by our suppliers in Bangladesh.
These are partners that have genuine expertise in making our trousers and with whom we are in close collaboration.
Thanks to this relationship of trust with our industrial partners, we can create high-quality technical products.
