What It Is

Top-rated winter jacket, bringing warmth, breathability, and a high level of rain protection along with a soft, comfortable fit. This jacket leads the way in demonstrating how a winter jacket should perform.
GORE-TEX Infinium™ WINDSTOPPER®

Gore-Tex® garments provide total wind protection and maximum breathability. The windproof membrane keeps you from getting cold due to windchill, but the optimum breathability prevents overheating and moisture accumulation by allowing sweat to escape easily. Water repellency is ensured by the DWR treatment applied to the outer fabric.

Polartec® Alpha® Direct

Rosso Corsa

Our Rosso Corsa label is only applied to the highest-level products we make. Every thread and fiber, every curve and contour is obsessed about. Rosso Corsa represents a categorical breakthrough in cycling innovation and the meticulous craftsmanship you expect from Castelli’s performance-enhancing apparel.

RoS - Rain or Shine

We’ve engineered RoS as the no-compromise best clothing we know how to make for dry conditions, and then tried to make it as close to waterproof as possible without sacrificing breathability and ventilation.

How a winter jacket should perform.

Cyclingnews.com says this jacket "sets an all-new benchmark in what a winter cycling jacket can achieve," and it's exactly what we think the perfect winter jacket should be. With this next generation, the Alpha Doppio RoS Jacket, we think we've made our best jacket better. 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 we 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 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. In this next generation, we used a softer, warmer Polartec® Alpha Direct insulating layer. Next, we made small changes to 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, we've created a stretch layer with a silicone bead that lies flat and completely seals out wind without bunching or riding up. We've made some updates to the double-layer wrist opening, with an inner layer that goes 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. This jacket will also hold up well in wet conditions, so we used GORE-TEX INFINIUM™ WINDSTOPPER® fabric along with waterproof seam taping on critical seams around the shoulders. 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. We call it "essentially waterproof," using our 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 we do longish rides in real rain and stay completely dry. All these features make it a favorite of our staff and most of our ambassadors, and the most versatile performance jacket for cold-weather training we've ever created.

Good update from the original Alpha ROS jacket

21/12/2023

I updated to this from the black original Alpha ROS jacket I have been using for several years to get: (a) red color for more visibility in the dim winter daylight, (b) the new Polartec material for the inner insulation, and (c) the various detail improvements. XL size for both, this newer vision seems slightly more "generously" sized than the original, perhaps just my impression. Disappointing that the red color is less bright than shown in the photo, not as eye-catching as the red in the Castelli scorpion logo or the Gabba2 long sleeve jersey I have had for a few years.

Veste très performante par grand froid

09/01/2024

C'est mon meilleur investissement en tant que produit habillement vélo, cette veste est extraordinaire, confortable et très efficace contre le froid en dessous de 5°C, car au dessus un peu chaude.
Par des températures négatives portée avec un sous-vêtement technique thermique (uniquement 2 couches, le sous-vêtement et la veste) je suis bien au chaud.

Excelente producto para salidas invernales en Burgos ( España)

Llevo varias salidas este invierno y es perfecta para climas duros de frío y viento como el que tenemos en Burgos. Soporta las temperaturas que dice con bastante fiabilidad.
