Giro Manifest Spherical Bicycle Helmets

Experience unparalleled protection, ventilation, and comfort with this advanced trail and enduro bicycle helmet, engineered for riders who demand premium performance. At its core is Spherical Technology powered by Mips®, a revolutionary ball-and-socket system that allows the outer liner to rotate independently around the inner liner during impacts. This innovative design effectively reduces rotational forces, enhancing brain protection without relying on traditional hard-plastic slip planes.
