WINDSTOPPER® Shell Fabric
WINDSTOPPER® Fabric is completely windproof and provides maximum breathability, keeping you comfortable longer across a wide range of weather conditions and activities.
The windproof membrane eliminates windchill and protects the warm, but highly sensitive, microclimate surrounding your skin. The 1.4 billion micropores in every square inch of the WINDSTOPPER® membrane also let water vapour from perspiration escape virtually unhindered, even when you’re working at maximum intensity.
How does it work?
The WINDSTOPPER® membrane is an ultra-thin protective layer that is laminated to a lightweight textile layer, making it totally windproof. It is made from the versatile polymer PTFE (polytetrafluorethylene) which is expanded to create a microporous structure. These micropores are 900 times larger than water vapour molecules, allowing perspiration to pass through unhindered. This means that the WINDSTOPPER® membrane makes any textile completely windproof, without perceivably restricting its initial breathability or weight.
Special Features
- soft, lightweight: provides insulating warmth without added weight
- warm, dry insulation: allows perspiration to easily escape keeping you warm and dry from the inside
- water resistant: sheds snow and water to protect the insulation and dries quickly.
