One key principle of the Vvolt design philosophy centers on safety and visibility - the Nutcase Vio helmet solidly ticks those boxes. 360 degree lighting keeps riders visible with a 200 lumen front light and a 65 lumen side and rear light. The lights run for 3 hours each full charge. The magnetic buckle eliminates the risk of under chin pinches and a removable visor keeps sun and rain out of your eyes. Dual density, two-piece construction utilizes MIPS technology to maximize head protection in the event of a crash.
