Castelli PRO ISSUE SS Short Sleeve Base Layer

Specifically requested by the pros for those inbetween conditions where mesh is too light, but an insulated baselayer is too heavy. Designed solely to transport moisture away from your body and help your race jersey perform at optimal levels, the Pro Issue SS base layer is just what the pro teams ordered. Using a 3D mesh fabric that creates dead airspace next to your skin, a polyester capillary moves sweat away from your body, keeping you dry.

• 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
• 10°-25°C / 50°-77°F
