The Alpha RoS 2 Cycling Jacket by Castelli stands as the epitome of winter wear, offering warmth, exceptional breathability, and rain protection in a soft and comfortable design.
Crafted from GORE-TEX INFINIUM™ WINDSTOPPER® fabric, the jacket's exterior boasts a lightweight material with a unique membrane that provides complete windproofing, high breathability, and water repellency, while also providing insulation.
Minimal seaming and seam-sealed shoulders prevent moisture ingress, ensuring protection during misty conditions, wet roads, and light rain.
The Alpha's exceptional insulation lies in its innovative dual-layer construction. Beneath the exterior layer, an internal vest provides close insulation suitable for temperatures down to -5˚C. This design allows for effortless temperature regulation so you can open the external layer to promote airflow and moisture evacuation without compromising insulation or exposing the body to wind chill.
A double-layer cuff seamlessly integrates with winter cycling gloves, while a lie-flat waistline ensures a snug fit to prevent cold air from entering at the jacket's openings.
The updated stretch fabric features a narrower panel between the shoulders and a wider front, delivering a close-to-body fit that minimises flapping and mirrors the body's shape on the bike. This new cut accommodates a wide range of body types and riding positions.
