Mountain biking is a demanding sport -- compromises and shortcuts when it comes to gear are never a good idea. The 4Forty is built to withstand the rigors of a trail-riding life; with generous ventilation, the comfort of Float Fit and built-in Sweat Guide, extended rear coverage, a full hard shell, adjustable visor and integrated MIPS protection. Boasting the comfort, protection and broadly capable features of helmets costing twice a smuch, the 4Forty is a bantamweight, all-conditions, all-kinds-of-trail champion packing a heavyweight value.
Fusion In-Mold polycarbonate shell - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
