The Castelli Alpha Doppio Ros Jacket presented by Escapa is a premium winter jacket with a soft, comfortable fit that provides warmth, breathability, and a high level of protection against rain. This jacket’s performance sets the standard for what all winter jackets should offer.

What Features Should a Winter Jacket Have?

Cyclingnews.com considers this jacket to “set a new benchmark for what a winter cycling jacket can achieve,” and, in fact, this jacket perfectly embodies our vision of what the ideal winter jacket should be. We believe we’ve elevated our jacket design with the Alpha Doppio RoS Jacket, part of this new generation of apparel. Even the best fabrics available today, which offer a good level of breathability, cannot absorb the sweat generated during a high-intensity ride. That’s why we’ve developed a double-layer structure that allows you to open the outer windproof layer while keeping the insulating layer closed, thereby allowing airflow inside the jacket to wick away moisture and prevent direct contact with the skin. On a long climb, we’ll fully open the outer layer to allow moisture to escape, and when we begin the descent, we’ll close the outer layer so our body stays completely dry. It works so well that it sometimes seems like magic. For this new generation, we’ve used a softer and warmer Polartec® Alpha Direct insulating layer. We’ve also made small adjustments to the openings: the collar, waist, and, most importantly, the cuffs. Its high collar is designed to move with you—whether you’re standing or in an aerodynamic position to attack your teammates and become the leader for the month of January. For the waist, we’ve created an elastic layer with a silicone band that stays flat and completely seals the garment against the wind without wrinkling or riding up. We’ve updated the double-layer wrist opening with an inner layer that sits beneath the glove to perfectly seal the wrist, and an outer layer that extends over the glove so rain runs down the outside of the glove and doesn’t penetrate inside. We also wanted this jacket to perform well on rainy days, so we’ve used GORE-TEX INFINIUM™ WINDSTOPPER® fabric along with waterproof tape on the most critical seams around the shoulders. Other seams are out of direct contact with water, so the fabric’s water-repellent treatment is sufficient to keep out most moisture. We call this “essentially waterproof”: our subjective take on the balance between water protection, breathability, and comfort. This doesn’t mean that a single drop of water will never get through, but the reality is that when we go on long rides in real rain, we stay completely dry. All these features make it the favorite jacket of both our staff and most of our ambassadors, as we’ve created the most versatile high-performance jacket for riding in cold weather.
