On average, over 85,000 people a year suffer traumatic brain injuries as the result of cycling accidents in the United States. We are Park & Diamond and it is our mission is to improve cycling safety with our collapsible bike helmet that can be rolled up into the shape of a water bottle. The helmet can be conveniently stored in the water bottle holder on the bike or easily carried in the water bottle pocket on a backpack or briefcase, meaning the helmet is either with you or on your bike so its always where you need it when you need it. The flexibility of the helmet and the incorporation athletic fabric means the helmet is form fitting and comfortable, and aesthetically looks like a baseball hat. By conveniently fitting an active lifestyle with a stylish and comfortable design, there is no longer an excuse to not wear a helmet.
