Castelli Pro Mesh W Sleeveless

The professional cyclists we work with know how important it is to choose a base layer that suits the conditions. The professional mesh fabric is suitable for a wide range 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 baselayer. We've given it a graphic print so you can show that when you unzip it, there's something special hiding behind your jersey.
