ALPINESTARS SM10 Deegan OR/PU/PK motocross helmet

Motocross Helmet ALPINESTARS SM10 Carb BLACK/YELLOW/ORANGE

• The design of the S-M10 offers a smooth, attractive, aerodynamic profile that is optimized and does not contain any external channels and elements that could act as a load point in an impact or disrupt the overall construction of the helmet.
• The curvature of the surface helps reduce friction on impact, allowing for deflection and the most efficient transfer of energy to protect the rider's head from direct force on the skull and carried to the neck and spine.
• The S-M10 shell sizing solution ensures that each helmet size has its own appropriate shell size to provide the most anatomical solution for the wide variety of fit needs around the world.
• Removable side pads made of semi-soft polymer for added protection provide a larger contact area to help distribute impact energy.
• The patented A-Head Fitment System allows easy adjustment of the angle and height at which the helmet sits on the head.
• Extremely ventilated helmet with 28 individual inlets and outlets, not including the eye hole, with 18 inlets and 10 outlets for optimal ventilation.
• Multi-directional Impact Protection System (MIPS). MIPS is a system designed to inhibit the rotational forces that can occur as a result of certain impacts and works by adding two low-friction layers that act against each other and essentially act as a skid plate to mimic the brain's own a low-friction fluid that is the body's natural defense against oblique impacts.
• Multidirectional Impact Protection System (MIPS). The MIPS system is designed to inhibit the rotational forces that can occur as a result of certain impacts and works by adding two low-friction layers that act against each other and essentially act as a slip plane to mimic your own cerebrospinal fluid with low friction, which is the body's natural defense against oblique impacts.
• ERS visor emergency release and new visor extension to provide sun protection.
• New extraction technology includes a helmet extraction system.
• Helmet composition:
• 20% POLYURETHANE, 17% POLYCHLOROPRENE, 16% CARBON FIBERS, 14% FIBERGLASS, 12% POLYSTYRENE (EPS), 7% ARAMID FIBERS, 7% POLYAMIDE, 4% POLYVINYL CHLORIDE, 2% STEEL and 1% EXPANDED POLYPROPYLENE
• Protection:
• The construction of the helmet shell uses highly advanced molding technology with a combination of several composites:
• 3K Carbon, a high-density carbon outer layer that improves strength and energy dissipation performance on the shell
• Unidirectional carbon composite layer that provides significantly greater radial strength around the shell, preventing compression but allowing controlled deflection to reduce transmitted impact energy
• A layer of aramid fibers that provides protection against critical penetration
• This combination of layers has even better characteristics thanks to the epoxy resin bonding, which provides the best possible strength and energy management; the limited deflection of the outer shell means that energy is spread more widely and absorbed better than the 4-density EPS shell.
