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.
A minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS).
GOGGLEGUIDE™Adaptable visor system accommodates both goggles and glasses and works with or without the visor attached.
MIPS®-EQUIPPEDMIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
NO-TWIST TRI-GLIDES™Quick-adjust fasteners that help keep straps flat and properly positioned
SWEAT GUIDE™Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
