Protection and Comfort without Limits

The Castelli Alpha Doppio RoS Jacket redefines the performance standard for winter jackets, offering complete protection against cold, wind and rain. With a design optimized to keep you warm and dry in the most demanding conditions, this Castelli jacket is ideal for cyclists who don't give up on the weather.

Innovative Weaving Technology

Equipped with GORE-TEX INFINIUM™ WINDSTOPPER® 150 fabric, this jacket guarantees advanced protection against wind and water. The Polartec® Alpha Direct insulation layer offers excellent heat retention without sacrificing breathability, allowing optimal temperature regulation at all times.

Exceptional Breathability

Thanks to its double-layer construction, the Alpha Doppio RoS allows for optimal ventilation without compromising insulation. The outer layer can be opened to wick away moisture and regulate body temperature, even during intense rides.

Water Resistance on Rainy Days

This jacket offers water-repellent protection with strategically taped seams at the shoulders, plus water-resistant treatment in other areas. While not completely waterproof, it offers reliable coverage that keeps moisture at bay in most situations.

Fit and Comfort in Motion

Designed with an ergonomic fit, the Alpha Doppio RoS features a high collar that adapts to different positions. The silicone-banded waistband stays flat against the body, while the double-layer cuffs provide a perfect seal to prevent cold air from entering.

High Performance Details

Featuring a water-resistant YKK® Vislon® zipper and rear pockets with reflective drainage holes, it also features a secure zippered pocket on the front for valuables. Weighing just 390g, this jacket is lightweight and functional, ideal for the most demanding cyclists.
