Just1 J39 Thruster Motocross Helmet

We want everything to fit right . Take some quick measurements if you are unsure of your current clothes size. The most accurate measurements will be those you take in your underwear, applying the measuring tape directly to your body.

Please note that the information in this size chart is not specific to the manufacturer's products as we currently do not have the manufacturer's original size chart. The details in the size charts are not binding and are for guidance only. If something does not fit you, of course you can exchange the goods with us (see FAQ Exchange / Complaint).
