Cut
This jacket has a slim fit. The 13% elastane fabric and "raglan" sleeves up to the neckline provide greater stretch and freedom of movement during your hike.
A warm layer, such as a fleece or light down jacket, can be worn underneath.
You can choose your usual size, or one size up if you don't want to wear it slim-fitting.
Hood
The adjoining hood is adjustable in height and depth with an elasticated drawcord. The rigid visor offers maximum protection for your face.
The little detail that makes all the difference: a triangular opening on the side of the hood for better visibility to the sides.
Jacket construction: 3 layers
This jacket is built with 3 layers, the best protection available on the market: the membrane is bonded between the inner and outer layers of the component (hence the name 3-layer component).
The membrane is a kind of very thin polyurethane film, which makes the component waterproof while remaining breathable.
It is protected by a knitted fabric, and has the advantage of being more flexible, lighter and often more breathable than a coating.
How to care for your jacket
This jacket has sealed bands (to guarantee perfect waterproofing) which are sensitive to machine washing and may come unstuck over time. We therefore recommend that you use a sponge and water to clean any marks on your jacket, and that you only wash it very rarely in the washing machine at 30°C, if you want it to last as long as possible on your hikes.
Waterproof test
Impermeability is measured by a fabric's resistance to water pressure expressed in mm water column (JIS 1092 standard)
The higher the pressure, the more impermeable the fabric.
The component in this product has an impermeability of 25,000 mm and therefore resists the pressure exerted by 25,000 mm water column.
This is also equivalent to 25,000 Schmerbers.
Breathability test
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: breathable fabric
RET ≤ 20: not very breathable fabric
Our product has a RET of 6.
How do you reactivate the water repellency of your jacket?
A fabric's water repellency is its ability to let water slide off its surface, without absorbing it. As a result, your jacket won't become waterlogged, and remains light and breathable. Water repellency is achieved by a treatment applied to the outer face of the fabric, but in use these properties can be altered.
All the steps to reactivate water repellency are described below:
