CASTELLI ALPHA ROS 2 JACKET
The CASTELLI Alpha ROS 2 Jacket is exactly what we think the perfect winter jacket should be. CASTELLI started with a list of things it didn't like about the current jackets and set out to solve them—and in the process make its best jacket ever.
The first issue to resolve related to moisture management. Even the best of the currently available fabrics provide a good level of breathability but can't keep up with the sweat generated during high-intensity riding. So CASTELLI invented a double-layer construction that allows you to open an outer wind-protection layer while keeping the insulation layer closed and thereby allowing airflow inside the jacket to evacuate moisture while avoiding direct contact with the skin.
On a long climb, we'll completely open the outer layer of the CASTELLI Alpha ROS 2 Jacket to allow moisture to escape, and when we start the descent, we close the outer layer and are completely dry inside. It works so well that sometimes it feels like magic. New for this year is a softer, warmer 3D insulation-layer fabric that provides better warmth, moisture management, and fit.
Next, CASTELLI focused on the openings: Neck, waist, and, most of all, wrists. The neck comes up high and is shaped to move with you, whether you're standing or in an aero position being a January hero and attacking your mates. For the waist, CASTELLI has created a stretch layer with a silicone bead that lies flat and completely seals out wind without bunching or riding up. New for this year is a brand new double-layer wrist opening with an inner layer to go under your glove that seals tight to your wrist, and an outer layer that goes over your glove so that any rain will roll down the outside of the glove and not end up inside.
Of course, the ultimate jacket will also hold up well in wet conditions, so CASTELLI used GORE-TEX INFINIUM™ WINDSTOPPER® fabric along with waterproof seam taping on critical seams around the shoulder. Other seams are hidden out of direct water flow, and the water-repellent treatment on the fabric is sufficient to prevent most moisture from entering. CASTELLI calls it essentially waterproof, using its own subjective judgment to find a balance between water protection, breathability, and comfort. It doesn't mean that no drop will ever come in, but CASTELLI does longish rides in real rain and stay completely dry.
All these features make the CASTELLI Alpha ROS 2 Jacket a favorite of the Team Ineos riders, and the most versatile performance jacket for cold-weather training CASTELLI has ever created.
WHAT IT IS
The CASTELLI Alpha ROS 2 Jacket is CASTELLI's ultimate jacket, bringing warmth, breathability, and a high level of rain protection along with a soft, comfortable fit. With a fresh update in its third generation, this jacket leads the way in demonstrating how a winter jacket should perform.
