    Our warmest winter cap has Gore-Tex Infinium™ Windstopper® protection on the front-facing surfaces, while we let sweat escape out the back with Warmer fabric. It's thick enough to provide warmth but takes minimal space under the helmet.

    Features
    • Comfortable fit
    • Gore-Tex Infinium™ Windstopper® X-Fast on front blocks wind
    • Warmer fabric on back for breathability
    • Cut to fully cover ears for warmth
