Windstopper is a windproof breathable fabric laminate made by W. L. Gore & Associates.
Unlike Gore's well-known Gore-Tex laminate, Windstopper is not waterproof.
Many Windstopper garments are marketed as "softshells" suited to high-output aerobic activities such as running, cycling or cross-country skiing.
However, because they are based on a solid laminate layer, they remain inherently less breathable than other wind-resistant "softshell" fabrics made by Polartec or Schoeller, which rely on built-in properties of the fabric and weave rather than laminates.
