The GMAX MX-46 pairs a lightweight shell with extensive ventilation for trail rides and motocross laps. Its solid matte-black finish keeps the look simple, while the large goggle opening, adjustable peak and washable interior make it a practical choice for regular off-road use.

The chart is a starting point. Try the helmet on and check for an evenly snug fit before riding.
The removable interior and mouth-vent filter can be washed according to GMAX's care instructions. Let them dry completely before reinstalling. A cold-weather breath guard, GMAX part 72-3407, is available separately.
