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. Add Goggles or your favorite eye protection, and get out there already!
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.
MIPS 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.
Fusion In-Mold polycarbonate shell – A process pioneered by Bell bonds the helmet’s outer shell to the EPS foam liner to create a sturdier helmet.
GoggleGuide Adjustable Visor – Accommodates both goggles and glasses
