The Castelli Men's Avanti Cycling Jersey is built on the brands' Competizione model. This jersey combines Strada micro mesh ventilated stretch fabric on front and back for great fit and moisture management with Tailwind dimpled stretch fabric on the sleeves, side panels and pocket for perfect fit. The Castelli Men's Avanti Cycling Jersey doesn't have overly tight fit, and the fabrics are stretchy enough to accommodate all body shapes.
