Built with PRO Transfer Mesh fabric , this ultralight jersey offers next-level breathability and quick-drying comfort to keep you cool when the pace and temps rise.

A GoFresh™ anti-odor treatment keeps you feeling fresher, longer. The compressive race fit delivers aerodynamic efficiency without sacrificing comfort, with thoughtful details like an elongated sleeve length and low-rise collar for a streamlined feel. A YKK semi-locking front zipper optimizes airflow, while three traditional rear pockets and a zippered stash pocket keep your essentials secure and within reach—no matter how hard you're pushing.
