The Castelli Mortirolo 6S Jacket is an invaluable addition to your cycling gear. Specifically designed for winter, it ensures you stay comfortably warm on those chilly rides without the risk of overheating. The combination of materials used in constructing this jacket offers the perfect balance of insulation and breathability, making it suitable for those who cycle intensely and tend to run hot.

Constructed with premium GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric on the upper chest and sleeves, this material not only offers impeccable windproof protection but also breathability. Its built-in fleece liner provides additional warmth and softness, keeping the cold at bay. The lower body, on the other hand, features a thinner version of the WINDSTOPPER® fabric for optimal ventilation.

At the back of the jacket, you'll find a highly breathable fabric that allows moisture to escape freely. This design element helps you maintain a stable core temperature no matter how vigorous your ride is. It's this attention to small details that sets Castelli apart.

To top it all off, the Mortirolo 6S Jacket is minimalist in design with a reflective panel on the chest for increased visibility in low-light conditions. The jacket also features three rear pockets, providing ample storage for essentials on your ride.

With a weight of just 337g, it's perfectly suitable for temperatures ranging from 6-14°C (43-57°F). The Castelli Mortirolo 6S Jacket is not merely an article of clothing but a statement that you're a cyclist who values performance paired with comfort and style.
