Estremo Thermal Winter Cycling Cap

Castelli Estremo Thermal Winter Cycling Cap

Combining exclusive Polartec AirCore on the front and Castelli's Warmer fabric on the back, the Castelli Estremo Thermal Winter Cycling Cap strikes the ideal balance of weather protection, warmth and breathability. Facing into the weather, Polartec AirCore, the PFAS-Free, electrospun, semi-air-permeable fabric, ensures cold winds are kept out and light rain is repelled. To the back, Castelli's Warmer fabric provides warmth and an easy escape route for sweat vapour, maintaining comfort when the pace rises or the terrain pitches upwards. With its peaked design and carefully shaped ear coverage, it's the ultimate headwear for cyclists riding through the harshest months.
