It has both better rain protection and improved breathability. It has two larger pockets that better complement the three pockets on the jersey you wear underneath this jacket.The new Perfetto Light is closer to a Perfetto Vest with sleeves, which makes it perfect for your spring and fall training and racing in cool conditions.WHAT IT ISWith just a base layer it's a wind-protection jersey for mild conditions.
