PRODUCT FEATURES
Our best jacket for mild winter conditions. This lightweight, super breathable and extremely fast jacket is great for high-intensity rides or when you want to maintain an optimal temperature in cold conditions. Alpha construction with membraneless outer layer and Polartec® Alpha inner insulation
Nano Flex Lightna woven fabric on the chest, sleeves and upper back partially protects against the wind, but the absence of a membrane ensures maximum breathability
The two-layer Alpha construction separates the wind-resistant and insulating layer, thanks to which it has better ventilation and thermoregulation.
Water-repellent finish
Polartec® Alpha active insulation on the chest, sleeves and back for thermal comfort
- Nano Flex Extra Dry on the back for better breathability, heat and sweat can escape, but it can protect against rain thanks to water-repellent treatment using nano technologies.

This is a jacket for a quick ride in cold weather, or if you want to dress just right in the transition period. What makes this jacket work in full gear is our two-layer Alpha construction, which will have you ready to race as soon as spring starts. The elastic fabric of the top layer allows some air to pass through so that you don't sweat as much during intense riding in the cold, because when you're wet, you'll be cold. The inner layer made of Polartec Alpha material insulates, but is breathable enough and is so light that you don't even know you have anything on.
We made the back from our Nano Flex Extra Dry, which insulates solidly, but thanks to the fact that it does not have a membrane, it breathes well and sweat can evaporate quickly. The sweater is on the body so that nothing flutters in the wind, and small details complete the whole: smooth-running YKK® zippers, reflective elements and drainage holes on the pockets, flat silicone hem on the waist. Precise fit makes it our most aerodynamic jacket. Not that aerodynamics are so important in winter, but we at Castelli believe that speed is fun.
