Extremely lightweight and breathable, the Castelli Fusione Jacket keeps out the wind and rain for the bicycle racer who doesn’t want to compromise their performance with a bulky, suffocating rain jacket. Besides blocking wind and repelling water, the Windstopper® Helium fabric is very packable so you can fold up the Fusione cycling jacket and easily store it in your back jersey pocket. You can pull the easy to grab “rip cords” and open up the zippered vents in the front and back when you need to let in air to cool down your body on those mountain climbs. The Thermoflex fleece-lined collar is really comfortable and you can flip it up to block out the wind. The mesh sleeve lining will feel comfortable against your skin. A Silicone gripper on the jacket’s waistband keeps it from crawling up and reflective piping all around makes you visible to motorists. Ideal for temperatures ranging from 40F to 65F (>5C <15C)
