What is the WINDSTOPPER® membrane?

The WINDSTOPPER® membrane is an ultra thin windproof layer laminated to the shell fabric of
the garment. The membrane delivers complete windproof protection, cutting out the wind chill
that lowers your core temperature.

Helping maintain your body’s optimum microclimate, the WINDSTOPPER® membrane is also
fully breathable. Its micropores are 900 times larger than water vapour molecules, allowing
vapour to escape to meet the demands you place on garments in active outdoor pursuits.
