Product waterproofing - 5000mm
Waterproofing is a fabric's capacity to prevent penetration of rain water. The resistance of a fabric to water pressure is expressed in mm of a water jet (test based on standard ISO 811). The higher the pressure, the more waterproof the fabric.
Material with a waterproof rating of 2000 mm resists the pressure exerted by 2000 mm of water (which roughly corresponds to a 2-hour rain shower).
Component breathability
To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).
The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is.
For example: RET < 9 = extremely breathable fabric
Care tips
Machine wash inside out on a synthetic programme at 30°C. Do not use too much detergent, and do not use softener.
It is best dried on a hanger in a warm, well-ventilated place.
