Castelli Alpha Doppio RoS Winter Jacket – GORE-TEX INFINIUM™ WINDSTOPPER®

The Castelli Alpha Doppio RoS Jacket represents one of the most advanced winter cycling jackets ever developed. Designed for serious training in cold and unpredictable weather, it delivers exceptional warmth, breathability and protection from wind and rain.

At the heart of the jacket is Castelli’s innovative double-layer Alpha construction, combining a GORE-TEX INFINIUM™ WINDSTOPPER® outer layer with a Polartec® Alpha Direct insulating layer. This unique system allows riders to regulate temperature more effectively during hard efforts while maintaining excellent protection from the elements.

The outer windproof shell can be opened to release heat during climbs while the insulating layer remains closed, helping keep you dry and comfortable even during high intensity riding.
