• FUSION IN-MOLDING SHELL: A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.

• MIPS-EQUIPPED & FLOAT FIT: 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. A minimalist, lightweight fit system with an easy-to-turn rubber over-molded dial for adjustments (integrated with MIPS).

• NO-TWIST TRI-GLIDES AND SWEAT GUIDE: Quick-adjust fasteners that help keep straps flat and properly positioned. The sweat Guide pad design pulls moisture away from the brow pad and away from eyewear

• GOGGLEGUIDE ADJUSTABLE VISOR: Adaptable visor system accommodates both goggles and glasses and works with or without the visor attached.

• VENTILATION: This helmet has 15 smallish vents in its shell. These holes are lined up with corresponding holes in the polystyrene liner and open-cell padding, and provide direct exit paths for hot air. Except for the vents in the chin guard and the ones over the years, the vents are not covered with any type of wire mesh
