Castelli Pro Issue SS Mens Sleeveless Baselayer - White
This is the piece our pros requested for those in-between conditions where the Prosecco R is too warm and the Pro 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
Reduced seaming at shoulders for extra comfort
Wider collar to fit under aero jerseys
Flat waist hem to lie flat in shorts
