Tech Style : The Invisible Bike Helmet

Two Women designers from Sweden have designed what could possibly be the coolest invention for stylish travellers. Hövding is a rapidly-inflating airbag that deploys from a collar around your neck when you’re in an accident.Powered by rechargeable battery-powered accelerometers and gyroscopes that detect the typical motions involved in a bike crash. They trigger a tiny gas inflator which instantly fills a nylon airbag with helium. The bag forms a hood around your head that cushions the impact.

Hövding costs $600 and only works once. But hey you cant put a cost on stylish life saving equipment? Or can you!
