About the brand

Giro has been engineering protection for riders since 1985, when founder Jim Gentes started rethinking the helmet from his garage in Santa Cruz, California. Four decades on, the brand remains a benchmark for head protection and optics on snow — pairing Mips® rotational-impact technology and dialed In Form™ fit systems with VIVID goggle lenses developed with Optics by ZEISS® that make flat light readable. From park laps to big-mountain lines, Giro gear is built so you can focus on the terrain instead of your equipment. At Mountain Sports, we love Giro because its helmets and goggles work as one system — seamless compatibility, honest fit, and proven protection for every day on the hill.

To measure your size: wrap a measuring tape around your head, keeping the tape level from front to back, then reference the chart above. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you have the right size, use the fit system to dial in the final adjustment.
