Since 1903, riders have expressed their identity with a Harley-Davidson. And for some riders, there's no act of self-expression more important than tying a turban. Inspired by the recent helmet-law exemption for Sikh motorcyclists in Ontario, Pfaff Harley-Davidson commissioned a new turban designed with three layers of protection – foam that hardens on impact, bulletproof composite fabrics and 3D printed armor. The designs have been open-sourced so any manufacturers can create tough turbans for riders around the world.
