A HELMETS IN YOUR SIZE
For a helmet to provide effective protection while
remaining comfortable, it has to be perfectly
suited to its user.
Choosing the correct size is essential.
• Measure the circumference of your head with
a tape measure, positioning it about 2 cm above
your eyebrows: this is where your head is the
largest. Once you have taken this measurement,
compare it to the table of sizes. Try the size of
SHARK Nano and SHARK Raw helmet closest
to the measurement obtained, starting with
the size smaller than your head measurement.
If you feel that the contact is too hard, try the
size larger.
Your head should be held quite firmly but you
should feel no discomfort.
• Tests for size must be carried out with the
chin strap tightened (please refer to the section
on page 6-7 for instructions on tightening the
chin strap). Check that you have good vertical
and horizontal visibility.
Check that your head can carry out all of these
movements without any particular discomfort.
• Check that when the chin strap is tightened,
the helmet cannot be removed from your head
when you try to move it forward by force. If the
helmet comes off or nearly comes off, it is too
big or else the chin strap is not correctly tighte-
ned. Keep trying on helmets until you find the
ideal size.
WARNING: do not lend your helmet, even for
a short journey, if its size is not perfectly
suitable. For each use of your helmet, it is
absolutely necessary to make sure that the
helmet is well positioned on your head, and
that the chin strap is properly adjusted, fol-
lowing the instructions of this manual (see
page 6-7).
