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.
- Main Fabric: 100% Polyester
- Panels: 85% Polyamide, 15% Elastane
