Technical Features

The most advanced model of Just1 is the J12. The goal was to produce a safe and comfortable motocross helmet for competition riders. The company has chosen a carbon outer shell for optimal strength. In addition, carbon is very light so the complete motocross helmet weighs only 1150 grams. A perfect fit is essential to provide good protection and performance. Just1 has therefore developed 2 shell sizes with impact damping foam and comfortable inner lining. This carbon motocross helmet is also equipped with an extensive ventilation system for maximum cooling of the rider. But this helmet is not only light, comfortable and protective, it also looks good! The J12 has aggressive styling and is available in a wide range of modern designs and colours. Every year there are new designs on the market, so keep an eye on this page!
