The HJC C70 Silon full-face motorcycle helmet is constructed from a sophisticated, ultra-lightweight Polycarbonate shell with a large visor cut-out for optimal vision. This comes in 2 shell sizes for added aerodynamics and features HJC's Advanced Channelling Ventilation System (ACS): full air circulation from front to back to dissipate heat and moisture up and out. It comes with a scratch-resistant inner sun visor. The main, clear visor is also anti-scratch treated and anti-UV with RapidFire Visor Replacement System, which allows quick and tool-free removal and installation. The C70 offers a great fit with pronounced comfort with removable, moisture-wicking lining with advanced anti-bacterial fabric and glasses grooves. The C70 is available in a choice of designs and colours.
