Castelli Mortirolo 4 Jacket

The versatility of the Castelli Mortirolo 4 Jacket keeps you warm when it’s cold, but the vents allow you to bring in cool air on warmer days. The adaptability of the Mortirolo makes it a year-in year-out favorite amongst cyclists. The jacket keeps you warm and thanks to the thermal Warmer fabric, sweat evaporates out the back. A piece of clothing may insulate in body heat, but if it doesn’t keep you dry you’ll get cold. Riding in a jacket that allows moisture to evaporate is one of the features of a performance piece of clothing and the Mortirolo is one of the top pieces for comfort on the bike when it’s cold outside. When it gets warmer, open up the zippered front vents and use a lighter base layer. The front zipper is easy to open and let in even more cooling air. The Gore Windstopper® on the front blocks out chilly wind, but Castelli didn’t add water repellency treatments as they did in the Perfetto jerseys and jackets. The Mortirolo is a great choice for high intensity riding on those dry fall and winter days. Details such as the silicone gripper at waist to keep the jacket in place and the three external rear pockets with reflective strap complete the features of a cycling jacket that offers everything a cyclist needs to stay comfortable when riding a bike in cold weather.
