Estremo Thermal Winter Skully

Castelli Estremo Thermal Winter Skully

Come the coldest months of the cycling season, the Castelli Estremo Thermal Winter Skully provides a cosy head covering, ensuring freezing temperatures and cold winds don't ruin the mood. Castelli's exclusive Polartec AirCore, a PFAS-free, electrospun, semi-air-permeable fabric, is deployed across the front, providing reliable protection from the cold and repelling light rain showers. Meanwhile, their Warmer fabric gives cosy warmth and extra breathability, regulating temperature as your effort levels vary, and the terrain rises and falls.
