The Regenerative Helmet is making bicycle helmets cool and comfy again. To be fair, they were never cool or comfy, so the Regenerative Helmet is breaking new ground here.
The Regenerative Helmet is made of a hard outer shell, with flexible materials inside which allow the helmet to conform to your head type. This is a revolution in helmet design. Helmets are typically bulky and loose, but this design is sleek and tight. Hopefully we see this on the shelves soon.
