Our Tuned Fit System allows a rider to dial in their fit using different thickness pads on the interior of the helmet. Our helmets always come with two sizes of pads. Each size comes in a different color which makes it easy to determine the right pads to fit the helmet to the head. It is very important to adjust the helmet with these included pads. For example, if necessary, the slightly thicker pads can be mounted on the back of the head and the pad for the front of the head can be thinner, or vice versa.
