Castelli Pro Mesh W Sleeveless

The cycling professionals we work with understand how important it is to choose a base layer that suits the specific conditions. The professional mesh fabric is suitable for a variety of conditions and is designed to keep you dry in cool to mild temperatures. On the coldest days, we even wear it under a Flanders Warm base layer. We’ve added a graphic print so you can show that when you unzip, there’s something special hidden behind your jersey.
