A pair of Swedish women have developed a remarkable solution for safety helmets: The Invisible Bike Helmet.

Tired of strapping ugly, uncomfortable styrofoam-and-plastic turtle shells to their heads, the pair came up with a revolutionary solution that does manage to give you full head protection without, remarkably, wearing anything on your head.

There’s also a new Inflatable Helmet. The airbag helmet is worn around the neck like a scarf or collar. The collar contains a folded up airbag that inflates in the event of an accident.

Sensors within the collar pick up strange or sudden movements. The airbag is shaped like a hood. It surrounds and protects the user’s head. (Natalie Portman wore one because of her character’s epilepsy in the movie Garden State!)

Then, of course, there’s lots more out there to choose from. And you can create your own personalized design…
