This is the piece our pros requested for those in-between conditions where the Prosecco base layer is too warm and the Core Mesh isn't quite enough, 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
