The Giro G10 Wireless Audio Series Helmet gives you DJ-quality sound to open the throttle over wide-open freeride terrain. An integrated wireless audio system works with your Bluetooth-enabled phone or MP3 player and can be removed so you can rock out all year long. Thanks to controls for volume, track select, play/pause, and call connect, you can call in sick and then shred to your favorite playlist without worrying about dropping your expensive toys in the snow. The G10 Helmet's wide-angle cut and gapless fit allow you to go huge off a backcountry booter and find your landing without blind spots—so go for the 900. In-mold construction gives you a low-profile fit, and you can adjust the 14 Super Cool vents on the fly to optimize air flow.
