Castelli Estremo Windstopper Skully

Castelli Estremo Windstopper Skully. When weather conditions call for maximum warmth, cyclists depend on the Castelli Estremo Windstopper Skully. It's constructed with Gore Windstopper X Fast fabric for windproof, water repellent protection that breathes to prevent overheating. Warmer fabric with a fleece lining retains heat and allows moisture vapor to quickly escape for dry comfort. Specially designed ear covers offer protection from cold winds. Wear it alone on cool days or under a Bicycle Helmet in colder conditions.
