Castelli Alpha Ultimate Insulated Jacket Dark Grey Black - XL

The Castelli Alpha Ultimate Insulated Jacket offers exceptional insulation with minimal bulk, making it a must-have for riders looking to maximise their winter performance. The fully waterproof and highly breathable Polartec NeoShell outer fabric has a high level of four-way stretch. This layer keeps out wind and heavy rain, while letting perspiration escape. Internal insulation is provided by the use of Polartec Alpha Active fabric, which provides excellent warmth at a very low weight and is breathable. The front has a zip for the insulating layer and a zipper for the outer layer, making it easy to adjust the level of thermal protection. This allows for better overall ventilation during a climb or an effort to face the descents with a dry body. Technical details complete a performance-oriented design.
