Great collaboration between Pro-tec & Vonzipper. Two of our favorite brands joined forces & greated the Snakey Design. This is the Helmet version. The low-profile Pro-Tec Vigilante Helmet takes matters of fit & versatility into its own hands. Instead of wearing a thin beanie beneath your helmet to get it to fit just right, Pro-Tec equips the Vigilante with the BOA fit system which easily adapts the helmet to different head shapes. Just Dial in your custom fit with the BOA system. New for this season is the Vent plugs that means that you can regulate Airflow in & out of your helmet. This helmet is perfect with the Von Zipper Feenom goggles. Von Zipper Feenom goggles are not included but available from The Board Basement (sold separately) Size Guide: MED fits 55-56cm LRG fits 57-58cm XLG fits 59-60cm XXL fits 61-62cm
