Built for race-day performance, this women's zip top uses ultra-light Adapto™ compression fabric with four-way stretch to deliver consistent support and breathability throughout hard efforts. Acrofuse™ bonded construction and lay-flat seams eliminate friction points, keeping the fit smooth against the skin over long distances. Four gel pockets at center back and an internal phone pocket at the back neck keep essentials secure and accessible, while reflective branding at the front and back adds low-light visibility.
