The Joe Rocket Canada RKT 200-Series Ion 3.0 motorcycle helmet has a modern, lightweight and low-profile aerodynamic shell design that's built with an A.T.P.A™ Advanced Thermo-Poly Alloy shell that meets or exceeds ECE 22-05 standards. It fits an intermediate oval head ship and while the neck roll is tight, it is not uncomfortable; this plays a big role in the fit but also in reducing wind that can travel up the helmet. The large chin intake vent and ram-air top intake vent forces in fresh air throughout the helmet for temperature control, making your ride more comfortable in warmer climates. The simple Press-fit Air Lock™ security system locks your shield in place, keeps everything secured at speed and the beveled shield helps to create a more optimal seal. As well as a bonus tint shield, the helmet also comes fitted with an easy to use internal sun visor with extended coverage so that it drops low enough to really help block sun and shield the eyes.
