Step 1: If the helmet has one, adjust the fit system at the rear of the helmet for a snug, secure fit. Some fit systems also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.

Step 2: Adjust the straps so that they sit just below the earlobes.

Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.

Step 4: Adjust the interior pads if needed.

Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.
