Product Details


Teach your kiddos early that wearing a helmet doesn't have to be a hassle with the Anon Define Helmet. Redefining the fit, style and coolness of youth helmets, the Define Helmet has a strong, ding-resistant ABS exterior, an ultra-comfortable classic fleece lining, and anon's exclusive Strapper-Keeper Technology so fussing over finicky goggle straps is never the cause of a lift-line meltdown. The Fidlock® Snap buckle utilizes magnetic closure to allow for pinch-free, one-handed closure even while wearing gloves.


Endura-Shell ABS ConstructionEndura-shell two-piece construction features an injection-molded ABS exterior for long-lasting durability and ding-resistant strength. Built for season after season of knock-around wear and tear, this is the pinnacle in reliable protection.


Passive VentilationPassive ventilation channels integrated into the helmet draw fresh air in the front and pull moisture out the back. These built-in channels help to keep goggles clear and aid in maintaining a balanced and comfortable climate all day long.
