Review SIMPSON Helmet

The Simpson OB31MD Open-Face Helmet is a top-tier racing accessory designed to offer superior protection and unparalleled comfort to motorsport enthusiasts. This helmet, engineered by Simpson Racing Products, is built to meet the stringent safety standards set by the Snell Memorial Foundation.

The OB31MD helmet boasts an advanced Aramid fiber composite shell, which is lightweight yet incredibly strong. Aramid fibers are known for their exceptional tensile strength and resistance to heat, making them an ideal material for racing helmets. The helmet's shell is also designed with a multi-density EPS liner, which absorbs and dissipates energy upon impact, reducing the force transferred to the driver's head.

One of the most notable features of the Simpson OB31MD helmet is its open-face design. This design provides excellent airflow, allowing for enhanced cooling and increased driver visibility. The helmet's chin bar is removable, allowing for a more customizable fit and easy access to the driver's face in case of a need to communicate or make adjustments.

The interior of the OB31MD helmet is lined with a plush, moisture-wicking material that helps keep the driver's head cool and dry during extended racing sessions. The helmet also features a multi-point, adjustable harness system that ensures a secure and comfortable fit. The harness system is designed to evenly distribute the forces of deceleration, reducing the risk of neck injuries.

The Simpson OB31MD Open-Face Helmet is available in various sizes to accommodate a wide range of head shapes and sizes. The helmet's exterior is available in a gloss black finish, and it comes with a clear Polycarbonate face shield that offers excellent optical clarity and offers protection from wind, debris, and other elements. The face shield can be easily removed and replaced if necessary.

In summary, the Simpson OB31MD Open-Face Helmet is a high-performance racing accessory that combines superior protection, unparalleled comfort, and a customizable design. Its advanced features, such as the Aramid fiber composite shell, multi-density EPS liner, open-face design, and adjustable harness system, make it an excellent choice for serious racers looking for the ultimate racing experience.
