Alpinestars SM5 Action 2 Helmet, Lightweight Protection for MX Riders, XL, Bright Red/Blue Glossy

Product description

• Lightweight outer shell made from impact resistant thermoplastic in three anatomical shell sizes, plus three individual EPS inner liner sizes with a combination of inner lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and protection.
• An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
• Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
• Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports
• Complies with Federal Motor Vehicle Safety Standard 218 (FMVSS 218). The SM5 conforms to ECE R 22.06.
