In many countries, wearing a bike helmet while cycling in public places is compulsory because it is proven to have saved lives. However, anyone who has ever applied one of these helmets to their heads knows that are definitely not a one-size-fits-all piece of equipment. An ill-fitting helmet means less protection, but they can require much trial and error to adjust correctly. The Regenerative Helmet overcomes this with its hard outer shell and flexible segments that allow the helmet to contort to provide a better fit. The liner uses dual density multi-impact foam to provide impact protection for both low and high speed accidents.
