A favorite in the pro peloton, Castelli’s Pocket Liner Jacket is an advanced, rain-thwarting garment of solitude. At just 174 grams, it's Team Garmin-Sharp’s go-to jacket for racing and training, and not just due to its minimal weight, but because it’s waterproof, breathable, and race cut. Made of Castelli’s eVent Pocket Liner fabric, this packable shell focuses on breathability, ventilation, and stretch. It has zippered vents on the sides and plisse stretch zones at the elbows and back for total range of motion. The Velcro-over-zip front allows for easy opening and closing when you’re on the go. A rear storm flap guards against wheel spray and Velcro sleeve cuffs can either seal out the elements or allow additional airflow through the arms.
