Fly Racing Freestone Helmet - XL-2XL - Red - Grey YGroup_7033469042733 and sides) thanks to MIPSConstruction: ConeHead Technology ConeHead is the developmental code name for a revolutionary new way to mould EPS foam for helmets. The new ConeHead acts like a crumple zone around the head to absorb and dissipate impact forces more effectively than current hard foam liners. There are two different densities of foam as well as two different foams with their own characteristics of recovery from impact and inter foam bond strength. Lightweight at 317.
