Owner’s Manual

While it is not possible for any helmet to protect the user against all foreseeable impacts and
accidents, proper use of this helmet will provide a far greater level of protection, in the event of an
accident, than if no helmet were worn. For a helmet to function properly, to help reduce the risk of
injury or death and for maximum protection the helmet must fit firmly on the head, and the retention
system must be securely fastened. With the retention system comfortably but firmly adjusted, it
should not be possible for the helmet to be removed from the head when pulled at the rear in an
upward and forward direction.
Helmet fit is critical to helmet protective performance. Different helmets fit differently due to
differences in design and construction. The correct helmet size can only be checked and confirmed
by physically fitting the helmet to the user. Always try the helmet on in a store, before purchasing
it, to be sure you are purchasing the correct sized helmet for you. If you are unable to find a size of
this helmet style that fits you properly, please try another certified helmet style.
To determine which helmet size to choose , first measure your head size by passing a tape
measure around your head approximately 2 cm above the eyebrow line. Use the largest
measurement from this process. Select the helmet size that closest matches this measurement.
CHOOSING THE CORRECT SIZE HELMET
WARNING - FOR ADEQUATE PROTECTION, THIS HELMET MUST FIT SNUGLY AND BE SECURELY ATTACHED
Since helmet sizes do not always match perfectly with this basic measurement, use the helmet size
closest to your head measure that fits snugly, but without pressure points.
CHECKING THE FIT OF THE HELMET
Grasp the chinstraps as seen in [SEE DIAGRAM 5, pg7] and expand the helmet opening. Slide
your head into the helmet. If the helmet does not fit snugly or if the helmet feels loose in any way,
you should try a smaller size. IT IS IMPERATIVE THAT THE FIT OF THE HELMET BE SNUG FOR
IT TO PERFORM PROPERLY. To check for proper fitting, place the helmet on your head. Make
sure the helmet lining fits snugly around your head and the cheek pads are pressed close on
your cheeks. There should be no space between your brow and the lining. Grasp the helmet on
each side with your hands and try to move the helmet up and down as well as side to side [SEE
DIAGRAM 2, pg5]. You should feel the skin on your face and head being pulled by the lining. If
the helmet is able to move freely without rubbing your skin, the helmet is too large and you need a
