Bell Sixer MIPS MTB Helmet Matte/Gloss Grey

The Boundary Breaker
The last thing you want to be thinking about in the middle of a long backcountry ride is your helmet. It should be well-ventilated and protect your head. And it should fit so well that you don't know it's there. The Sixer takes to the trail with our integrated MIPS technology, resulting in a sleeker, closer-to-the-head fit that combines with a Float Fit system and proprietary Sweat Guide to ensure unprecedented comfort in a helmet. Goggle compatibility, complete with a strap gripper at the rear of the helmet, adjustable visor height, integrated camera/light mount and a full hard shell round out the package.

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. Progressive layering is the process of engineering a helmet liner with variable eps foam densities to better manage the transfer of energies after some impacts.

Fit system
Float fit race - a state-of-the-art lightweight fit system featuring seamless integration with MIPS, an easy-to-turn dial, wide-range vertical adjustment and padded width-adjustable cradles.
