Castelli Estremo Thermal Winter Cycling Cap - AW26

Warm winter accessories are essential.

Castelli's warmest winter cap has Polartec® AirCore™ protection on the front-facing surfaces and Warmer fabric on the back to let sweat escape. It’s thick enough to provide warmth but takes up minimal space under the helmet.
