Keep the winter rides rolling along with the protective and versatile Castelli Mortirolo 4 jacket. It’s constructed from Gore® Windstopper™ X-Fast fabric on the front for total windproofness with a water-repellent finish, while Castelli’s Warmer thermal fabric on the back provides massive breathability. A brushed fleece lining supplies insulation while also reducing moisture build up. Two zippered chest vents allow for adjustable airflow control, and there are three jersey pockets at the back for ample storage.

Available in multiple colors. Reflective tabs at the back for enhanced visibility.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

Great winter jacket

I've been riding with this jacket for the last few weeks and it's been a lifesaver. If you are riding in freezing temperatures, or below, this jacket is perfect. I have ridden with just a long sleeve baselayer and this jacket down to 30 degrees and have been perfectly comfortable, and down to 25 degrees with adding just a light wind-jacket over the top. The fit on this jacket is true to Castelli's standards. It is true form-fit which allows you to wear this like a jersey, and has the three large back pockets to allow you to go out all day. The water-repellent finish is a nice touch, but definitely isn't enough for anything more than road spray or a light drizzle. Though, it's not so bulky that you couldn't throw a rain coat over it to stay dry.
