Please note that the following recommendations are a starting point and do not replace personal advice from a sporting goods store.
Fitting: Try on several helmets if possible. It is important that the dimensions of the helmet fit the size of your head and that the helmet noticeably encloses your head.
Correct positioning: Make sure that the helmet is positioned levelly on your head. The helmet should not sit too tightly on the back of your head, which leaves the forehead unprotected, nor be pulled too far down over the forehead, where it can affect your vision.
Firm fit: You can test if your helmet sits firmly by shaking your head lightly with the chinstrap open. The position of the helmet should not change. An optimum fit is required for the helmet to fulfill its safety function 100%.
Adjustment: With the adjustable sizing system, you can fully customize the size of your helmet. To do so, place the helmet in the proper position and turn the wheel – clockwise to make the helmet tighter, counterclockwise to make it looser. The chinstrap should fit tightly, but should not hinder your breathing or swallowing. The chinstrap should always be closed while riding.
