Features:

• 3D mesh fabric for excellent moisture management
• Waist hem stays flat under shorts
• Suited for riding temperatures from 59-80F
• Lightweight
• Performance fit:Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit e.g., if you typically wear a Medium, select a Large in Castelli.
