Every certified helmet must carry a certification label inside. The Snell Foundation maintains a listing of all helmets that have met the Snell Standards. Manufacturers are required to put a Snell serialized label inside each of their Snell certified helmets by the Licensing Agreement. Before you buy a helmet, verify it's certified using the lookup tool or individual standards lists. Please note that Snell Foundation does not sell helmets, you would need to contact local or online dealer to get one.
