The job you want your helmet to do is to help absorb impact force when your have a fall, or when you are unlucky enough to be kicked by a horse. If your helmet does not help absorb this “energy”, then this extra energy can be transmitted through to your head, which means a greater chance of serious injury. To do its job then, a helmet should stay firmly in place on your head in an impact. To stay firmly in place a helmet needs to:
>Fit well
>Have the straps correctly adjusted to minimize movement
