Once you've determined
your preliminary tape measurement, select the helmet that is closest in
hat size to the tape measurement. If it is between sizes, round-up to
the next largest size. Now try on your helmet.
If you are not familiar
with helmets, you should use these instructions on the proper procedure
for putting one on:
Grasp the helmet by the chin straps, with the front of the helmet
facing you and the top of the helmet facing down.
Place your thumbs on the inside surface of the straps and balance
the helmet with your index fingers.
Spread the helmet apart with your hands, and slip it down over
Helmets of different
shapes go on differently. Sometimes, the front of the helmet must go on
first; other times, the rear. If the helmet flops down on your head with
no resistance, you have your first indication that it may be too large.
Obviously, if it won't slide down over your head at all, it is too small.
Many people unfamiliar
with helmets are reluctant to pull down if they meet resistance as the
helmet goes on. To tell if it is really too small, or just snug going
on you should continue the effort to get the helmet on. Only if the helmet
is impossible to put on should you move up to the next size, as helmets
that go on snug generally fit very well once on all the way.
Remember, most people
will select a helmet that is too large for them. They will regret it later,
because ill-fitting helmets are more likely to be noisy, windy and fatiguing
We have noted that
some people have a tendency to wear a helmet perched on the backs of their
heads, like hats. Be sure that the helmet is sitting squarely on your
head. Use the location of the eyes in the eyeport of a full face model
as a gauge.
The eyes should be
approximately in the center, with the top edge of the liner padding just
above the eyebrows.
