“Rather than looking like a hunk of foam, the Park and Diamond helmet is nearly as thin as a baseball cap while remaining just as protective as something more traditional. The helmet can be collapsed, folded, rolled, and stuffed into a water bottle or pocket.”

“This collapsible helmet could save lives.”
