A few decades ago, helmets were rarely seen, except for on extreme athletes or the overly fearful. Today, we’ve realized the importance of protecting our skulls, and many countries have enforced mandatory helmet laws for cyclists. Speaking to this are a wide range of helmets, available in a range of innovative designs.

We’ve seen aesthetically pleasing helmet covers, eco-friendly bamboo caps, helmets for clumsy toddlers, and helmets with supplementary functionality like wireless technology. There are even helmets out there with no safety features at all, like the luxury scalp massager. Creative marketers caught onto the trend, and made an attempt at “headvertising.”
