The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.

The membrane protects against water and wind penetration, whilst allowing water vapour generated during exercise to escape. A waterproof rating of at least 10,000 mm water column acts as a barrier against rain and snow, whilst breathability helps regulate moisture inside the garment. This solution enhances comfort during activities in changeable weather conditions.
