The shell of this helmet is composed of various pieces and components that have been certified to meet the DOT FMVSS No. 218 safety standards. This certification ensures that the helmet provides the necessary protection for the rider's head in the event of an accident.

The shell itself is constructed using a durable and impact-resistant material, designed to withstand the forces and stresses encountered during a collision. The shell is the primary component that shields the rider's head from direct impacts, distributing the force across its surface to prevent serious injury.

In addition to the shell, the helmet also features a range of other pieces and components that work together to enhance its overall safety and performance. These include the lining, padding, and retention system, all of which play a crucial role in ensuring a secure and comfortable fit.

The lining, typically made from a soft and absorbent material, helps to cushion the rider's head and provide additional impact protection. The padding, strategically placed within the helmet, further enhances the comfort and stability of the fit, while also contributing to the overall energy-absorbing capabilities of the helmet.

The retention system, comprising straps and a secure fastening mechanism, is designed to keep the helmet firmly in place on the rider's head during an accident. This system ensures that the helmet remains properly positioned, providing the necessary coverage and protection for the rider's head.

The DOT FMVSS No. 218 certification process involves rigorous testing and evaluation of these various pieces and components, ensuring that the helmet meets or exceeds the safety standards set forth by the U.S. Department of Transportation. This certification provides riders with the confidence that their helmet will perform as intended, offering reliable protection in the event of a crash.

In summary, the shell, lining, padding, and retention system of this helmet have all been carefully designed and engineered to meet the DOT FMVSS No. 218 safety standards, ensuring that the rider is provided with the necessary protection and peace of mind when taking to the roads.
