Castelli Estremo WS Skully Black UNI Beanie

Warm 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.

GORE-TEX INFINIUM™ WINDSTOPPER®

• Gore-Tex® garments provide total wind protection and maximum breathability. The windproof membrane keeps you from getting cold due to windchill, but the optimum breathability prevents overheating and moisture accumulation by allowing sweat to escape easily. Water repellency is ensured by the DWR treatment applied to the outer fabric.

Features

• GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast on front blocks wind
• Warmer fabric on back for breathability
• Cut to fully cover ears for warmth
