The Giro Source MIPS helmet is designed for fun and adventure, combining advanced performance and protection in a rugged, trail-ready design. It features deep coverage with aggressive ventilation from 17 vents coupled with deep internal channeling to keep you cool. The helmet includes the comfort and secure feel of the Roc Loc™ 5 MIPS fit system with Integrated MIPS brain protection, a moto-style adjustable screw-in visor, and full lower Hardbody durability. The Integrated MIPS® Brain Protection System aims to reduce rotational forces while enhancing fit and comfort. Giro's proprietary Wind Tunnel ventilation system actively thrusts fresh cool air over and around the rider's head. The Roc Loc® 5 Fit System offers benchmark comfort, stability, adjustability, and weight savings, allowing for one-handed customization. The tool-free bolt-on visor is easily adjustable for various riding positions and goggle storage. The In-Mold construction permanently fuses a polycarbonate shell to the foam liner, eliminating adhesives and excess weight, with the Hardbody design enhancing durability. The adjustable moto-style screw-in visor allows for easy one-handed adjustment while riding. Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older. Weight: 340 gr.
