Bell 4Forty MIPS MTB Helmet Matte-Gloss/Black Camo
$129.99
The Off-Road Achiever
Mountain biking is no doubt, a very demanding sport. Bell know's 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 Science in Motion
MIPS uses a slip-plane system that moves inside the helmet, mimicking the brain's own protection system. This layer is designed to rotate inside the helmet with the intent to potentially slow or reduce the amount of energy transferred to or from the head. Science tells us that if we can reduce the strains associated with rotational acceleration, we might reduce the risk and severity of brain injury. In an accident the head rotates quickly and comes to a sudden stop, the rotational acceleration can cause the brain tissue to experience high levels of strain. The stretching of the tissue that can be caused by these motions can result in various types of brain injury.
Construction
Fusion in-mould polycarbonate shell a process pioneered by bell bonds the helmet's outer shell to the eps foam liner to create a sturdier helmet.
Fit system
Float fit a minimalist, lightweight fit system with an easy-to-turn rubber overmoulded dial for adjustments (integrated with MIPS)
