A Helmet In Your Size; The Chin Strap - Shark Spartan GT Carbon Owner's Manual

A HELMET IN YOUR SIZE

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 appropriately and
the chin strap adequately 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 ob-
tained lies between two sizes, start by
trying the smaller helmet. Keep in mind

that due to the wide variation in skull
shapes, these references merely serve
to guide you to the size best adapted to
your particular head. To ensure efficient
protection, 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 positioned above your eye-
brows. Also ensure that the chin strap is
sufficiently tightened, as shown on the
following page.
1. The head must be fully enveloped by
the helmet and the cheek pads must pro-
vide adequate support. Should this not
be the case, the helmet you selected is
too big, so try the next smaller size (see
Figure 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. You should feel your skin
stretch around the head and face when
