This road helmet is a direct descendant of the pro-level Z20, bringing that level of advanced engineering and design to a women's model. It's the perfect combination of minimal weight, aero efficiency, and cutting-edge comfort technologies to help you climb, sprint or ride from dawn until dusk. The integrated Float Fit system offers comfort and security with a streamlined fit and a rubber-coated dial that's easy to adjust on the fly. The Overbrow Ventilation system pulls cool air in through the front and pushes it through an air-channel matrix to minimize drag and prevent overheating. And the adjustable No-Twist Tri-Glides keep the straps flat and properly positioned. Perfect fit, perfect form — from the start line to the podium.
