These helmets' sculpted ventilation and hip styling are great for bikers on the go. The clean lines and easy-to-use features are thoughtful touches that offer everything you need - and a little more than you expect.

All helmets are constructed with in-mold technology that fuses a tough outer microshell to the helmet's EPS foam liner. The fusion process reinforces areas around vents and ribs, making the helmet lighter, cooler and tougher. With Giro's Acu Dial system you combine single-handed adjustment with a full-fit band for a quick, sure fit. Helmets feature vents that allow cool, fresh air in and stale, warm air out.

The Revel and Trinity fit heads 54-61cm in circumference and are carefully sculpted and size-specific to simplify the fitting process. The Bishop fits heads 58-65cm circumference. All of Giro's helmets comply with U.S. Consumer Product Safety Commission's safety standards for bicycle helmets.
