Foldable

Park and Diamond, an innovative fold-able helmet is designed by ex-SpaceX engineers. Although it looks like a traditional baseball cap, it never compromises safety. The Park and Diamond helmet will pass all U.S. and E.U regulations to make sure you get the protection you need while riding a bicycle or kick scooter. Adult sizes will be available first. The Park & Diamond Bike Helmet’s patented protective material absorbs and dissipates three times more elastic energy than a traditional bike helmet, which means significantly less energy is being transferred to the head, and making the Park & Diamond Helmet a better bike helmet.
