Clear, quality stereo speakers in the Giro G9 Audio Series Helmets ear pads set the soundtrack for your day of riding, and no one else will know that Forever in Blue Jeans is what really gets you pumped for a fast-and-dirty tree run. And to save your skull from an unfortunate arboreal encounter, the G9 Helmets outer hard shell and fused EPS liner work together to deflect and absorb impact. The helmets venting system draws cool air into the front and lets warm air escape out the back, so youll stay comfortable from ridgeline to lift line. A helmets function is only as good as its fit, so use the built-in In-Form Fit System dial to customize.
