DOT motorcycle helmets are tested for safety and quality standards that are set by the Department of Transportation. They are tested to make sure they will with-stand a crash and the proper materials are used to manufacture them. Some of the requirements are shock absorbancy and crash impacts. When you order a DOT approved motorcycle helmet you can be sure that you are receiving a helmet that is tested to save you life and reduce injury to your head.
*Helmets are non-returnable, for safety reasons.
