| 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 standard): this component resists 5,000 mm H20 (Schmerbers) before washing (equivalent to the pressure exerted by a 5 metre column of water). |
| Fabric water-repellency |
The fabric of this jacket is water-repellent, i.e. water runs off its surface without being absorbed. This prevents the fabric from soaking up water and keeps it lightweight and breathable. The water repellent property is achieved by treating the fabric's exterior. In addition, we taped the main seams that are most exposed to the rain. |
| 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 do you maintain the waterproofing quality of your jacket over time? |
To maintain a durable 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 programme) - with a hair dryer at a distance of 20 cm by going back and forth twice
- or two strokes 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/duration of the physical effort. If the breathability of the fabric is not adapted to your type of physical activity, the perspiration vapour condenses inside the jacket. You will feel damp inside: It is not rain coming through but perspiration vapour condensing. Choose your jacket according to your type of physical activity. This 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. |
