Legal Half Helmets v/s Full-Face Helmets

While half helmets may be legal in California, it is very important to look into the potential risks that come along with limited coverage of half helmets. Half helmets are enjoyable, lightweight and handy but comparatively they are less protective.

Full-face helmets on the other hand, provide complete protection to head, face, ear area, and chin. That’s why full-face helmets are always safer than the half helmets. They protect you from impact, facial injuries, debris, dusty wind, and insects. It makes no sense asking, “Can I wear a half helmet in California?” if you have habit of riding so fast.
