They’re essential pieces of safety kit, made from specialised materials. But F1 helmets do far more than just protect the driver. F1 Explains explores helmet design, testing and technology with Stephane Cohen, co-CEO of Bell Racing – the company which makes helmets for 13 current F1 drivers.  Stephane tells Katie Osborne and Christian Hewgill how Bell make helmets that are strong and light, visors that don’t fog up and why a car update can require helmets to be modified.  Plus, hear how F1 helmets differ from those worn by the stars of the NFL.
