Waterproof fabric
The waterproofness of a fabric, ensured by a coating or membrane, is measured in Schmerber or mm H20 (pressure exerted by a column of water). The higher the number, the more waterproof the fabric.
This jacket is designed with a coated waterproof component (JIS 1092 standard): this component resists 5000 mm H20 (Schmerber) before washing (i.e. the pressure exerted by 5 meters of water column).
Breathable fabric
Le tissu de notre produit est très respirant - 12 RET
La respirabilité d’un composant se mesure par sa “Résistance Évaporative Thermique”. C'est sa capacité à laisser échapper la vapeur d’eau produite par le corps pendant l’effort vers l’extérieur. Plus le coefficient de Résistance Evaporative Thermique (RET) est faible, plus le tissu est respirant.
RET < 9 : tissu extrêmement respirant
RET <12 : tissu très respirant
RET < 20 : tissu respirant
RET > 20 : tissu peu ou pas respirant.
Your health at the heart of our design
We have changed the composition of our water-repellent treatments to use PFC (perfluorocarbon) free technologies.
PFC is used to make a textile water-repellent.
How to keep your jacket waterproof?
We recommend reactivating the water-repellency of the fabric on a regular basis.
This can be done every 3 washes (a thorough rinse is essential), or after ten or so uses in the rain.
You can easily reactivate the water-repellency when hot:
- with your tumble-dryer for 15 minutes (synthetic program);
- with a hairdryer at a distance of 20 cm, going back and forth 2 times;
- or 2 passes with the iron, set on delicate without steam function.
Choosing the right waterproof jacket for your sporting activity
This rain jacket is designed for a 2-hour hike at a maximum pace of 5 km/h, with no change in altitude.
During sporting activities, we sweat more or less depending on the intensity and length of the effort. If the breathability of the fabric is not adapted to the effort, perspiration vapor condenses inside the jacket. You're wet on the inside: it's not the rain that penetrates, but the perspiration vapor that condenses. You need to choose your rain jacket according to the type of effort you'll be making.
