The starting point for selecting the right size is measuring the circumference of your head, a finger width above the eyebrows (the head size range is given in cm)
Correct positioning:
Make sure that the helmet is positioned levelly on your head. The helmet should not sit too far back on your head, which leaves the forehead unprotected, nor be pulled too far down over the forehead, where it can affect your vision.
Adjust the size properly:
With the adjustable sizing system (IAS system), you can fully customize the size of your helmet. To do so, place the helmet in the proper position and turn the dial at the back of the helmet clockwise to make the helmet tighter, counterclockwise to make it looser. The helmet should basically fit, the size adjustment should only be for fine tuning.
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%.
Adjusting the strap system:
a) Remove the comfort cushion on the chinstrap.
b) Close the ratcheted closure.
c) Set the length of the chinstrap by pulling on the outer strap.
The chinstrap should fit tightly, but should not hinder your breathing or swallowing!
d) Reattach the comfort cushion.
