C. Check for a correct fit. With the helmet on, go through the following checklist to determine
whether the helmet is the correct size.
1. Check whether the helmet inner lining fits snugly all around your head.
2. Check whether the top pad presses closely on the top of your head.
3. Check whether the cheek pads are in contact with your cheeks.
4. Check to make sure there is no space around your brow under the inner
lining, where you can insert your fingers.
5. Now, take hold of the helmet with a hand on each side. Without moving
your head, try to move the helmet up and down, and side to side. You
should feel the skin of your head and face being pulled as you try to move
the helmet. If you can move the helmet around easily, it is too big. Try a
smaller size.
D. Check the reten�on system and go through the following steps.
1. Fasten the chinstrap as �ght as possible without causing you pain.
There must be no slack in the strap and it must be �ght up against your
throat.
2. With the chinstrap secured, put your hands flat on the back of the
helmet and try to push the helmet off by rota�ng it forward.
3. Next, put your hand on the front of the helmet above your forehead (or
on the chin guard) and try to push the helmet off by rota�ng it toward the
rear.
4. If the helmet starts to come off either is too large for you or the chinstrap
is not enough.
