CASTELLI ULTIMATE ALPHA JACKET | MAN

For serious winter rides in all conditions, the Alpha Ultimate Insulated Jacket delivers premium insulation and extreme versatility. Castelli’s Alpha RoS 2 Jacket sets a new standard in winter riding comfort. The Alpha Ultimate Insulated takes it up a notch with a stretchier fabric and Alpha insulation that provides warmth without the bulk. The jacket is lighter and more comfortable, with similar levels of warmth and breathability. In fact, it’s almost 30% lighter, and stretchier for even greater comfort. It’s the fabrics that make it possible. The Polartec® NeoShell® fabric on the outside is completely waterproof and highly breathable, and also has 4-way stretch. This layer keeps wind and rain at bay while allowing sweat to escape. The insulation layer is made of Polartec® Alpha® active insulation fiber, which provides incredible warmth for its weight, while promoting breathability. It’s not just the fabrics that make this jacket great. On the front, there’s a zipper for the insulation layer and another for the outer part, so you can open the outer part to manage ventilation while keeping the insulation layer closed. This allows you to benefit from better overall ventilation when climbing or during efforts, while staying drier when you close your jacket for the descent. All the other features have been carefully considered to make this model your ideal winter jacket.
