Bell 4Forty Helmet 2018

Bell 4Forty Helmet Gunmetal / Tropic

All-mountain value – optional integrated MIPS, Float Fit, Sweat Guide, adjustable visor, full hard shell—the 4Forty is ready for anything the trail throws your way. The only thing missing is a triple digit price tag.

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 the option of integrated MIPS protection. Boasting the comfort, protection and broadly capable features of helmets costing twice as much, the 4Forty is a bantamweight, all-conditions, all-kinds of trail champion packing a heavyweight value.
