Have you heard about the Invisible Helmet "Hovding". It's not for motorcyclist yet, but for bicyclist. CRAZY! It's a helmet made of a small, helium gas cyclinder with abnormal motion sensors that inflate into an air-filled cushion around the bicyclist head when detecting an impact within 0.1 second. The invisible helmet is a removable fabric collar,folded airbag that is visible only on impact. It will be easy to carry and will come in different removable styles and fabrics. It is supposed to come out this spring. Not sure if once it is inflated you have to buy a new one or if you can repack it. It would be great if they make one for us motorcyclist. Especially, for the ones that persist on not wearing a helmet. Until then, I'll keep my motorcycle helmet on.Hammerdownbiker.com
