Water resistance of the fabric
The waterproofness of a fabric, provided by a coating or membrane, is measured in Schmerber or mm H20 (pressure exerted by a column of water). The higher this number, the more waterproof the fabric.
This jacket is designed with a waterproof coating (JIS 1092 L standard): this component resists 5,000 mm H20 (Schmerbers) before washing (equivalent to the pressure exerted by a 5 metre column of water).
Fabric breathability
Our product's fabric is extremely breathable - 12 TER
The breathability of a component is measured by its "Thermal Evaporative Resistance". This is its capacity to let out water vapour produced by the body during activity. The lower the Thermal Evaporative Resistance (TER), the higher the breathability of the fabric.
TER < 9 = extremely breathable fabric
RET <12 = very breathable fabric
RET < 20 = breathable fabric
RET > 20 = slightly to not at all breathable fabric.
How to maintain your jacket's waterproof quality and resistant
To maintain a resistant water-repellent fabric, we recommend reactivating it regularly.
Do this every three washes (it is important to rinse abundantly) or after a dozen uses in the rain.
You can easily reactivate the water repellent property by warming the fabric:
- in a tumble dryer for 15 minutes (synthetic program) - with a hair dryer at a distance of 20 cm by going back and forth twice
- or two passes with an iron on the delicate setting without the steam function.
Choose your waterproof jacket according to your sports effort
During sports activity, the extent to which we perspire depends on the intensity or the duration of the physical effortIf the breathability of the fabric is not adapted to your type of physical activity, the perspiration vapour condenses inside the jacketYou will feel damp insidethis is not rain coming through but perspiration vapour condensingSo you need to choose your jacket according to your type of physical activityThis jacket is designed for the occasional one-day hike at a speed of 5 km/h
Recommended additional product
To protect the lower body as well and have a very effective outfit to protect you against the wind and showers, we recommend the men's NH500 over-trousers. These over-trousers are also eco-designed (depending on the colour, a bulk dyeing process that reduces the consumption of water or recycled fibres are used)
