Featuring many of the same materials and technologies as Giro's top-of-the-line Synthe, the Saga Helmet offers a lightweight, aerodynamic option for those of us who demand performance that doesn't break the bank. The Saga features In-Mold construction, a process that unifies the EPS foam liner to the polycarbonate shell to create a structure that is lighter, stronger, and ultimately safer. The Saga offers a sleek aerodynamic shape and offers 22 Wind Tunnel vents to keep you cool and comfortable. Giro's Roc Loc 5 retention system is 40% lighter than the previous version and allows you to the adjust tension and vertical position of the helmet with the simple turn of a dial, making it super easy to find the perfect fit.
