There’s no doubt that wearing a motorcycle helmet is better than not wearing one, but various studies have shown that there’s one potentially-lethal injury that they don’t protect against - rotational injury, also known as intracerebral shearing. When a rider’s helmet hits the road, its rigid shell catches against the pavement and causes the helmet to very rapidly twist around. The rider’s head twists with the helmet, but does it so quickly that the brain doesn’t quite keep up, moving a few milliseconds after the skull it’s contained in. The result is the shearing of nerves and blood vessels, resulting in disabilities or even death. Lazer Helmets is now offering something claimed to reduce the risk of this injury by almost 70% - helmets with skin.
