Exterior and interior construction

When you see this Shiro MX 917 motocross helmet for the first time, you will perceive that it is a product with a high level of quality, due to the robustness of its structure and well-crafted finishes, both outside and inside. In addition, it has a great aesthetic appeal due to the colors of the casing.

For its manufacture, a series of certified and highly resistant materials were used, which is what is ultimately required in a product of this type, since it will be exposed to impacts and sudden weather changes that may arise on the track.

For this reason, the material selected for the shell was composite carbon, which is a combination of polymer with carbon. In this way, a structure with greater resistance to abrasion and great lightness is obtained. 

This last feature is quite convenient if we plan to wear the helmet for long periods of time, since it will not cause discomfort in the shoulders or neck. 

For its part, inside the shell there is a padding system with a lining in Dry Max and Cool Max fabric, which, thanks to its composition of polyester fibers, manages to absorb moisture and provides rapid drying, since it is a Quite breathable fabric.
