CastelliMen's Cold Days 2nd Layer(Return to Product Page)

I was skeptical at first with the mesh design, but it works. No cold sweat here. Paired with a quick dry shirt or mesh Castelli 2.0 shirt and Castelli fly jacket. It keeps me dry even after 2 hours of riding. It is lightweight and packable. Only drawback IMO is the fabric looks delicate, but so far it is holding up well. This is a must for cold winter months.
