Helmet ventilation is usually positive quality, but when temperatures are near freezing, you need a little something extra between your helmet and your head. Introducing the Castelli Estremo Wind Stopper Skully.
Constructed from WindStopper X-fast fabric, the skully provides maximum wind protection. A soft, moisture wicking fleece fabric is used on the inside to retain warmth. To improve compatibility with Castelli jackets, the long tail on the back of the skully is designed to tuck into the back of your jacket for a full coverage fit.
Beat the cold this winter with the Castelli Wind Stopper Estremo Skully.
