If you want versatile, trail-ready coverage with sacrificing performance, then choose the Giro Rift Sport helmet. The Rift brings features and styling inspired by Giro's premium trail riding helmets, like durable In-Mold construction and a removable visor, to recreational riders. In-mold construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows us to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets. Plus, fit adjustments are fast and easy to make with the Acu Dial system, and 24 big vents pull in cool fresh air to enhance comfort in almost any conditions.
