All-mountain value &horbar optional Integrated Mips, Float Fit, Sweat Guide, adjustable visor, full hard shell &horbar 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.
Integrated Mips (Multi-Directional Impact Protection System) is designed to reduce rotational forces that can result from certain impacts. By integrating the Mips slip plane into the retention system, Bell is able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.
A minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with Mips®).
Adjustable visor allows for sun protection and easy goggles storage.
Quick-adjust fasteners that help keep straps flat and properly positioned
