True, we lived, but many others got seriously injured or worse. Think of it as cheap insurance. A properly fitted and adjusted helmet will not only help prevent serious head injuries, but it also can be easy to use, cool your head as you ride, and look good to boot. You will you protect yourself and will be setting a good example for younger riders.

So be safe, be cool, and wear a helmet.
