At the foot of Mont-Blanc, our team of enthusiasts designed this breathable jacket for mountain walking on a regular basis and providing protection in a storm Rain will no longer hold you back! Thanks to its waterproof membrane, this jacket will keep you dry. Optimal comfort guaranteed thanks to it lightweight, stretch component while remaining breathable.
The fabric used for this jacket was chosen to reduce its environmental impact.

Sizing and fit information
Fitted cut to fully benefit from the stretch component. The so-called "raglan" sleeves go up to the collar for superior stretch and more freedom of movement when hiking. A warm layer, such as a fleece or light padded jacket can be worn underneath. The inner volume means that this jacket can be worn with a fine lightweight second layer, such as a fleece or light down jacket.
Adjustable height and depth with elastic drawcords and toggles. Semi-rigid visor with integrated mesh headband to provide a high level of protection. The small detail that makes the difference: a triangular opening on the side of the hood for better visibility to the sides.
Double tightening with an elastic cord and toggle at the jacket hem. Optimised wrist coverage and a tightening Velcro strip.
- A coating is like a kind of paint applied to the inside of the fabric that makes the component waterproof while remaining breathable. It is often less costly than a membrane, and requires a lining for protection. - The membrane is a kind of very thin plastic film (polyurethane) that makes the component waterproof while remaining breathable. It has the advantage of being more flexible, lighter, more durable and often more breathable than a coating.
Jacket construction with membrane
- 3 layers: The membrane is glued between the outer and inner fabric. Used for durable high-performance jackets - 2.5 layers: The membrane is glued under the outer fabric and protected inside by a fine film. Used for lightweight jackets. - 2 layers: the membrane is only glued to the outer fabric; the inner protective lining is free. Used for comfortable jackets
Waterproof rating of the component
The resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the ISO 811 standard). The higher the pressure, the more waterproof the fabric. A component with a 10,000 mm waterproof rating, i.e. it can withstand the pressure of the 10,000 mm column of water. This is also equivalent to 10,000 Schmerbers.
Waterproof rating of the jacket
This garment has been validated in a shower test under 100 L/m²/h of water for 3 hours. This test reproduces the average conditions of a storm in the mountains.

To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more water vapour generated by physical activity is able to escape, and the higher the fabric's breathability. For example: RET ≤ 3 = extremely breathable fabric RET ≤ 6= very breathable fabric RET ≤ 12= breathable fabric RET ≤ 20 = little or no breathability
How to restore the water-repellent properties?
The water repellent property of a fabric is its ability to make water run off its surface without absorbing it. The water-repellent property is obtained by applying a treatment to the outer surface of the fabric. This treatment needs to be restored during the lifetime of the garment (every 3 washes).

A score for comparing the products' environmental impact
The product's environmental impact is calculated over its entire life cycle using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, trousers, backpacks, etc). Decathlon is committed to displaying the environmental information of its products. For further information: http://sustainability.decathlon.com/
Dry this waterproof protective garment thoroughly before storing it.
Our design team is based at the foot of Mont Blanc, in Haute-Savoie (France). All year round, we create and develop products that are attractive, simple and technologically advanced. We then test them ruthlessly in the field because we believe that the only way to continually improve is to conduct tests in the real-life conditions that you will experience.
