Alpinestars SM5 ACTION 2

• The S-M10 shell sizing solution ensures each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide, providing 4 different helmet shell sizes S, M, L, and XL and 6 consumer sizes from XS to XXL to ensure riders have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an 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.
• Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head.
• Ultra-ventilated helmet with 28 individual intake and exhaust ports, not including the eye port, with 18 intakes and 10 exhausts.
• New eject technology includes the eject helmet removal system.
• Lightweight ECE 1260g and 1310g with side pads and 1370g with visor extension.
