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.)

Waterproofing is a fabric's ability to prevent rain water from passing through. A fabric's waterproofing is determined by measuring its resistance to the pressure exerted by a water column, measured in mm (test based on ISO 811 standard). The higher the pressure, the more waterproof the fabric. The fabric used is waterproof to 5000 mm, meaning that it resists the pressure of a 5000 mm water column (which is about the same as a 3-hour downpour).

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 12 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 the back: 1 large, secure pocket (dimensions: 19 cm x 27 cm) for useful bits and pieces:
(tyre lever, tissues, etc.) that you can access with one hand, even when wearing gloves!
- The rain jacket folds up into its pouch, and can easily be stored in your bag.

Length: 28cm
