We first wrote about the Hövding ""air bag for your head" bicycle helmet back in 2010. Since then, we've seen that it won't just help you avoid helmet hair, but it has been called the safest bicycle helmet and won the world's largest design prize.
The Invisible Bicycle Helmet
is a short documentary (above) that follows Anna Haupt and Terese Alstin, two designers behind Hövding and how their innovative design came to be.
