Giro Source MIPS Bike Helmet

In-Mold Construction: In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.

Roc Loc® 5 Fit System: After more than two-years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.

Wind Tunnel™ Ventilation: Giro helmets are developed utilizing the proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

16 Vents with Internal Channeling

MIPS® Equipped: MIPS technology is designed to reduce rotational force to the brain in certain types of glancing or angled blows - this is accomplished by allowing the inner frame of the helmet to move slightly relative to the outer shell.

Adjustable Moto-Style Screw-In Visor: This visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow, allowing you to easily adjust your visor with one hand while riding.
