Castelli Pro Issue SS


Dry is good.

This is the piece our pros requested for those inbetween conditions where the Flanders is too warm and the Core Mesh is too cool, like Spain in February or Belgium in April. You’re not looking for warmth from your base layer, just something to move the moisture away from your body and help your race jersey perform. Our 3D mesh fabric creates dead air space next to your skin, while the polyester capillary action moves sweat away.


  • 100% polyester 3D mesh fabric

Castelli base layer

Excellent product absorbs sweat and keeps jersey dry, easy to wash and drying quickly

Castelli cool base layer 😎

Bought two of these for Mallorca training week now moved to 2022. They're perfect for early summer wear and I use in winter under a Castelli Expresso Due super warm winter jacket. Great value and comfortable. I prefer the short sleeve version if only it keeps your jersey fresher for longer.
