The Bell Sixer MIPS helmet is made from a Fusion In-Mold polycarbonate shell.Features:- Weight: 395 g- 26 openings , 4 front ports- Fusion In-Mold Polycarbonate Shell- Progressive layers- Fit system: Float Fit integrated with MIPS- Visor adjustable to 4 positions- Integrated camera support- Flat belt clamping system- Adjustable Google Guide visor system- Padding with anti-sweat guide- X-Static Pads- Sizes S (52-56cm), M (55-59cm), L (58-62cm)Technology:- MIPS: MIPS leads in the market for slip plane technology in the helmet’s interior which is designed to reduce any rotational impact from certain knocks. When the head rotates rapidly and comes to a sudden stop, the rotational acceleration can cause high levels of stress in the brain tissue. The tissue strain caused by these movements can result in various types of brain injuries. We believe that helmets equipped with MIPS technology bring the highest level of protection against certain types of impacts.
