NEW ARAI VX-PRO4 HELMET | STARS AND STRIPES BLACK FROST - SIZE XS The latest expression of the ultimate off-road helmet, the brand new VX-Pro4 evolved from the much-loved VX-Pro3 model. So it’s still the perfect choice for MX, enduro, and off-road use. Just as in every Arai helmet, the basic and simple organic shell shape is based on the R75 shape concept. The absence of exaggerated edges or protrusions on the shell should not be mistaken for a lack of imagination. It’s a visual demonstration of our commitment to maintaining the integrity of the shell with real-world impact performance.
