Castelli went back to the design table to come up with a better way to make a removable-sleeve jacket and in the process created a brilliantly versatile jacket. The zippers sit just above the elbow and cover 3/4 of the circumference of the arm. With the sleeves in place, you have Castelli's top-performing Perfetto RoS long-sleeve jacket. Remove the sleeves and you have a real Gabba to wear with your Nano Flex arm warmers
