The G9's freestyle inspired looks and state of the art protection helps give you the confidence to stomp that new trick you've been working on. The G9 Helmet's impact- absorbing foam liner takes the brunt of huge impacts, so your brain doesn't have to. The tough polycarbonate outer shell will take multiple seasons of small hits. Once you get tired of the park, hike the ridge for some freshies. Giro gave the G9 helmet 12 vents to keep you cool and comfortable on the way up. If the temperature drops and the wind picks up on top, plug the vents with the included Weatherstrip vent plugs. The G9's ample venting and light weight make it an excellent choice for backcountry riding as well.
