The Pro Issue W base layer is designed to wear under your cycling jersey on cooler race days - or slower rides in warmer weather. Unlike our core mesh the Pro has a 3D filled in mesh making it excellent at wicking moisture from the skin. This in turn keeps you drier and more comfortable than not wearing a base layer and balances out the hot sweaty up / cold damp down phenomenon you often get with cycling in the wrong clothing.
- 100% polyester 3D mesh fabric
- Reduced seaming at the shoulders for extra comfort
- Double layer neck line
- Flat waist hem sits better under shorts
- Sizes XS-XL
- Weight 38 g (S)
- Castelli comfort range under a racing jersey 15-25c
