GORE® WINDSTOPPER® PRODUCT TECHNOLOGY

The GORE ® WINDSTOPPER® membrane is an ultra thin protective layer which is laminated to a lightweight textile layer, making it totally windproof. It is made of the versatile polymer PTFE (polytetrafluorethylene) which is expanded to create a microporous structure. These micropores are 900 times larger than water vapor molecules, allowing perspiration to pass through unhindered.

The totally windproof, yet extremely breathable membrane blocks the wind and allows vapor to escape. This combination of protection and breathability minimizes the wind’s chilling effect while reducing the risk of overheating when you are active.
