Performance resistance of your jacket
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.
Waterproof jacket components
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
The fabric of this jacket is breathable: RET=12.
The breathability of a component is measured by its "Thermal Evaporative Resistance" (RET).
This is its ability to let water vapor produced by the body during exertion escape to the outside, thus preventing the accumulation of water on the skin.
The lower the RET value, the more breathable the fabric.
RET ≤ 6: very breathable fabric
RET ≤ 12: not very breathable fabric
RET ≤ 20: not very breathable fabric
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.
