Choose Your Size - shark SPARTAN RS Manuel D'utilisation

WARNING! No helmet can
fully protect users against
all possible high or low-speed
shocks. To ensure an efficient
level of protection however, the
helmet must be sized appropria-
tely and the chin strap adequa-
tely tightened, as indicated in the
manual. It is hazardous not to use
a correctly sized helmet or not to
sufficiently tighten the chin strap
closing system since the helmet
may become detached from the
head in the event of an accident,
thereby causing serious or even
fatal injuries.

CHOOSE YOUR SIZE

Each helmet, sized from XS to XXL,
has been designed for a given head
shape. To accurately measure your
head circumference, unroll a tape
measure horizontally at a 2.5-cm
distance above your eyebrows. If
the measurement obtained lies
between two sizes, start by trying
the smaller helmet. Keep in mind
that due to the wide variation in
4
skull shapes, these references me-
rely serve to guide you to the size
best adapted to your particular
head. To ensure efficient protec-
tion, you'll need to verify that the
helmet fits your head snugly. When
choosing a new helmet, be sure to
verify that your head slides all the
way into the helmet, with the top
line of the field of vision being po-
sitioned above your eyebrows. Also
ensure that the chin strap is suffi-
ciently tightened, as shown on the
following page.
1. The head must be fully enve-
loped by the helmet and the cheek
pads must provide adequate sup-
port. Should this not be the case,
the helmet you selected is too big,
so try the next smaller size (see Fi-
gure A).
2. With the chin strap appropriately
tightened, make sure the helmet
does not shift too much from left
to right and from top to bottom.
