THE HALFSHELL HERO

With a novel ball-andsocket design, Giro’s Manifest Spherical is the ultimate defense against traumatic brain injuries. By utilizing multiple planes the helmet can, upon impact, slow the brain’s movement inside your skull. Hit your head, and the socket skullcap incrementally rotates on the ball of the inner helmet, slowing rotational forces, by utilizing a MIPS low-friction slip-plane. A polycarbonate spine overlays dual-density foam that’s not overly stuffy, as 19 vents keep you cool and protected. $260; giro.com
