Technical information


To allow you to ride along the trails without worrying about branches and leaves, our design team selected a fabric with a tight weave.
The result? An authentic rainproof mountain biking jacket that can deal with all sorts of rubbing during your ride (hydration pack straps, branches, etc.)

What is a waterproof fabric?

Waterproofing is a fabric's capacity to prevent penetration of rain water. The resistance of a fabric to water pressure is expressed in mm of a water jet (test based on standard ISO 811). The higher the pressure, the more waterproof the fabric. This fabric used is waterproof to 2000 mm, meaning that it resists the pressure of a 2000 mm water column (which is about the same as a 2-hour downpour).

Is this fabric breathable?

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).

The fabric we have used has a breathability rating (RET) of 8 on a scale out of 40
The lower the rating, the more the fabric lets through the water vapour generated by your body during exercise


Carry the essentials on your rides, and access them easily:
- On your chest: 1 zipped pocket for your phone (phone size: L= 24 cm, W = 14 cm)
- On the back: 1 zipped pocket for useful bits and bobs (tyre lever, tissues, etc.) that you can access with one hand, even when wearing gloves! It is also designed for you to pack the jacket into it.
- 1 side pocket for 2 cereal bars.
- 1 multi-purpose side pocket.

Product tests

Our team of product designers based at the B'Twin Village in Lille is continuously working to make cycling more comfortable for our users.
Our obsession is to create products that meet the specific cycling needs of our users and eliminate things that get in the way of their rides.


A product's environmental impact is calculated for its entire life cycle using various indicators.
An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, trousers, backpacks etc.).

Decathlon openly displays the environmental ratings of its products.
