Castelli Alpha RoS 2 W Jacket

The Castelli Alpha RoS 2 W cycling jacket for winter is Castelli's flagship winter garment and is suitable for temperatures down to -10 degrees Celsius.

Double-layer construction for optimal performance
This cycling jacket features a double layer to offer you the best performance. The outer layer is made of windproof material to protect you from cold winds in winter. Often, such a windproof outer layer reduces breathability. That's why Castelli has added a second layer! The inner layer fits comfortably around the body, providing good insulation and keeping you warm. The wind is kept out by the outer layer, and if you get too warm, this layer can be opened with a zipper so that excess heat can still escape through the outer layer. Ideal for a long climb or intense interval training, for example. You can simply open the windproof layer to provide temporary ventilation, while the inner insulation layer continues to envelop your body. We have never seen such a warm cycling jacket with such good breathability.
