-25%  $82.45

List Price:  $109.95

All-mountain value & mdash; optional Integrated Mips, Float Fit, Sweat Guide, adjustable visor, full hard shell — the 4Forty is ready for anything the trail throws your way. Mountain biking is a demanding sport — compromises and shortcuts when it comes to gear are never a good idea. The 4Forty Mips 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 as much, the 4Forty Mips is a bantamweight, all-conditions, all-kinds-of-trail champion packing a heavyweight value.
