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.

An impregnation technology that is based on long paraffin chains that wrap spirally around individual thread or yarn fibres, forming a very thin layer. This layer reduces surface tension so that water droplets and even mud particles run down the surface of the fibre, while maintaining breathability.
