Launched in 2011, Just 1 is a relatively young Italian helmet brand that has already gained worldwide popularity. The company was started by Tony Amoriello, an avid off-road enthusiast, who was passionate about making a better version of any helmet options available on the market at that time. Amoriello has cooperated closely with the most successful motocross racers to develop helmets that include everything needed to allow both professional riders and amateurs perform at their best. Just 1 already boasts several world titles, including the 2016 MXGP and 2015 MX2 FIM Motocross World title with Tim Gajser and the 2013 MX3 title with Klemen Gercar.

Just 1 offers a wide range of helmets for off-road and adventure riding, all designed to provide the ultimate in protection and comfort. Everything from entry-level options featuring a high-quality thermoplastic resin shell to high-end models with a full carbon external shell, you’re sure to find the helmet that’s right for your needs and budget. At Just 1, they realize that proper ventilation is essential for both long-distance travels and off-road adventures, so all helmets the company offers are designed to maximize airflow to your head. With multiple air vents that allow for effective extraction of heat from your head you will enjoy a cool and comfortable ride in warm and hot weather. Just 1 helmets also come with a metal membrane on a chin air vent to prevent debris from penetrating inside your helmet.

When it comes to comfort, Just 1 helmets are hard to beat. Inside they feature a breathable moisture-wicking inner lining that allows for fast sweat evaporation to keep your head dry and cool in all conditions. What’s more, this lining has an antimicrobial hygienic treatment to prevent bacteria growth and eliminate odors. It is fully removable, washable and enables you to easily put on a helmet, ensuring a perfect fit. For extra security and safety, Just 1 helmets come with a double D-retention system. You can also find plenty of options with a J.1.E.R. emergency cheek pad removal system that allows the helmet to be easily removed in case of an accident. Plus, Just 1 offers helmets in a variety of colors and graphic designs so they will not only protect you from a head injury but will also complement your riding gear and help you stay stylish during your adventures.
