Specially designed for sports with high physical activity. GORE WINDSTOPPER ® Active Shell is absolutely windproof and protects against loss of body heat due to the wind chill effect. In addition to this, it is water-repellent and fast-drying. Maximum breathability allows for the escaping of water vapor and prevents overheating or moisture build-up within the clothes. The two-layer weather-protection membrane is very light and easily stowable.
