WINDSTOPPER® Fabric provides total windproofness while maintaining maximum breathability to keep you comfortable in a wide range of weather conditions and activities.
WINDSTOPPER fabrics are soft and lightweight to provide insulating warmth without added weight. They allow perspiration to easily escape, which keeps you warm and dry from the inside, even when you're working hard. They’re also water resistant, and shed snow and water. Finally, they dry quickly.
WINDSTOPPER® high-performance fabrics are made by laminating a windproof membrane to the inside of a functional fabric to prevent windchill while protecting the warm yet highly sensitive microclimate that surrounds your skin. The WINDSTOPPER membrane has 1.4 billion micropores in every square inch to let water vapor from perspiration escape virtually unhindered, even when you're working at maximum intensity.
How does it work?
The WINDSTOPPER membrane is an ultrathin protective layer that is laminated to a lightweight fabric, making the fabric package totally windproof. WINDSTOPPER membrane is made from 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. This means that the WINDSTOPPER membrane adds total windproofness to any textile without perceivably restricting its initial breathability or weight.
DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.
