Giro's Revel is a comfortable, all-around helmet that's ready for any adventure. In-Mold construction means it's light—so light you might even forget you're wearing it. And, the Acu-Dial retention system offers an easy-to-adjust custom fit. 22 large vents allow air to flow through the helmet as you ride, keeping you cool and comfortable. It also sports a removable visor to keep the sun out of your eyes when you're heading down the road.
