No head protection device can prevent all head injuries that may be sustained while participating in soccer or other sports, and the Storelli Head Guard does not, and is not designed to, prevent concussions.

In addition, for maximum performance, the Head Guard must be sized and fitted properly in accordance with the manufacturer's fitting instructions.
