Rearview Helmet

Reevu is the name of a company that makes a helmet with built-in rear view technology.

The helmet uses a series of mirrors running from the front to the back, to bend the light all the way around your head. The result is a front and back view, very similar to the set up in an automobile.

The mirrors are not made from traditional glass however. It's made of a reflective polycarbonate material that's unbreakable and lighter.

Here's what it looks like wearing the helmet..
