What It Is
The ultimate winter jacket somehow combines warmth with light weight, the feeling of freedom with full protection, waterproof fabrics with breathability. With the functionality of Castelli's Alpha construction.
Lightweight fabric designed for clothing worn during physical activity of long duration and intense effort in extreme conditions. Extremely breathable, waterproof and windproof. Offers maximum freedom of movement and protection.
For serious winter riding in all conditions, the Alpha Ultimate Insulated Jacket brings premium insulation to this do-everything-well jacket. Castelli's Alpha RoS 2 Jacket set a new standard in winter cycling comfort. The Alpha Ultimate Insulated takes that up a notch with stretchier fabrics and Alpha insulation that provides warmth without bulk. The jacket feels lighter and more comfortable, with similar warmth and breathability. In fact, it's almost 30% lighter, with more stretch to feel even more comfortable. The fabrics make it possible. The fully waterproof and highly breathable Polartec® NeoShell® outer fabric has a high level of four-way stretch. This layer keeps wind and rain out while also letting sweat escape. The insulation is Polartec® Alpha® active insulation, which provides incredible warmth for its weight while also aiding in breathability. Fabrics alone don't make the jacket. The front has one zipper for the insulating layer and a separate zipper for the outer shell, so you can open the outside for ventilation while keeping the insulating layer closed. This allows for better overall ventilation during a climb or effort, yet you'll be drier when you close everything back up for the downhill. All the other features are carefully considered to make this your ultimate winter jacket.
