OFF-ROAD ACHIEVER. 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 as much, the 4Forty is a
bantamweight, all-conditions, all-kinds-of-trail champion packing
a heavyweight value.
