FULL-ON FUN\n\nMountain 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 the option of integrated MIPS protection. Boasting the comfort, protection and capable features of helmets costing twice as much, the 4Forty is an all-conditions, all-kinds of trail champion.
