CASTELLI ESTREMO THERMAL INTER SKULLY Under-Helmet Cap Black

Designed for freezing conditions, the CASTELLI ESTREMO THERMAL INTER SKULLY Helmet Liner Beanie Black pairs windproof, breathable Polartec AirCore fabric at the front with a soft fleece Warmer lining at the back, which is less exposed to the wind but needs to wick heat and sweat.

Unlike the Estremo Thermal cap, it has no peak and features a closer fit for a minimalist profile under your helmet. It covers the ears completely and weighs barely 50 g for virtually no bulk. One size, engineered for the coldest rides down to -5°C.
