NanoSphere Technology: Most waterproof garments have a coating on the outside which is meant to prevent the outer shell from saturating with water. This Durable Water Repellency (DWR) coating hinders breathability and the function of the DWR in the long term and after washings greatly reduces. Although this does not necessarily mean that the product is no longer waterproof, it is not comfortable to wear a damp and poor breathable jacket. With NanoSphere technology, the structure of the surface is altered so no water drops or other fluids can adhere to this fabric. The result is optimum breathability and durable dry outer shell.
