We have been following this product since last year from its concept to a real Invisible Bicycle Helmet called "Hödving". Designed by Terese Alstin and Anna Haupt it makes a big steps now on a real market. It's ergonomic, it's practical, it complies with all the safety requirements, and it's also subtle and blends in with what else you are wearing. Worth to mention Invisible Helmet is made for people who prefers good looking to personal safety (yes, you) and especially when riding a bike (have you ever saw a fixed-bike lover with that bulky still safety helmet from a nearby store? No).
