Helmet Size Guide

To know what helmet size you are, you must measure the circumference of your head. For this you can help yourself, for example, with a measuring tape or a thread. Take the measurement approximately 25mm (1 inch) above your ears, where the circumference is greatest. Once that value is obtained, you will find your corresponding size in the following table. We stongly recommend that in addition to head size, the shape of your head is also taken into account and even if the measurements correspond, there is no substitute for trying on your selected helmet to ensure a safe, comfortable fit.

Shell Sizes

By making more outer shell sizes than most other manufacturers, LS2 helmets can offer a more consistent ratio of padding thickness to helmet size. This means that smaller helmets don't suffer the weight penalty of having too big a shell, while larger sizes aren't restricted by space to the amount of shock absorbing liner material they can use.

To ensure the best combination of safety and comfort, LS2 helmets utilise up to six outer shell sizes for some models.
