Premium protection meets advanced motocross design. The Just1 J22F Dynamo Motocross Helmet delivers lightweight strength, exceptional ventilation, and race-ready features. In addition, it comes with a free pair of Just1 Nerve Goggles valued at R1530, giving you full-face protection and crystal-clear vision from the start.

Firstly, the 3K carbon fiber shell, combined with the S.D.C Sequential Density Construction, absorbs impact efficiently while keeping weight low. Consequently, it provides high-level protection without compromising comfort. Meanwhile, four shell and EPS/EPP sizes allow a precise, personalized fit for every rider. Furthermore, the Impact Visor Release System reduces injury risk in collisions, and the E.R.C Emergency Removable Chin Bar / Cheek Pad System allows safe helmet removal when needed.

Inside, the PROTX2™ antimicrobial liner is removable and washable, keeping the interior fresh and hygienic. At the same time, the fully ventilated EPS-lined chin bar, along with the 9 intake and 6 exhaust ventilation ports, ensures continuous airflow. Additionally, the integrated vented roost guard protects from dirt and debris, while the helmet’s DOT and ECE certification provides verified safety compliance.

Sizing

To determine which helmet size fits you best, measure the widest circumference of your head using a flexible measuring tape or piece of string; approximately 2cm above your eyebrows and ears as illustrated below. If your head measurement falls between two sizes, it is generally recommended to select the smaller of the two.

For maximum safety and comfort, take note of the following points when fitting the helmet (and securely fastening the chin strap):

• Helmet may take some effort to slide over your head, but should not be overly difficult
• Should fit snuggly around the crown of your head without creating uncomfortable pressure points
• The top padding presses on the top of your head
• The cheek pads press against your cheeks, so that your teeth touch the inside of your cheeks when opening / closing your mouth
• There should be no space to slide two fingers between the helmet and your temple
• Hold the helmet on either side and without moving your head, try to move the helmet up and down, and side to side. It should not be easy to move and you should feel the skin of your head and face being pulled
• Your eyes should be located in the center of the helmet's viewpoint
