S-m10 deegan helmet | ALPINESTARS

Product description

The S-M10’s design offers a smooth, attractive, aerodynamic profile which is streamlined and free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet’s construction.
The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider’s head from direct force to the skull and referred to the neck and spinal column.
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.
Removable side pads made from a semi-soft polymer for added protection provide a larger contact area to help spread impact energy.
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, for optimum ventilation.
Multi-directional Impact Protection System (MIPS). MIPS is system designed to impede the rotational forces that can result from certain impacts and works by adding two low friction layers which act against each other and essentially act as a slip plane to mimic the brain’s own low friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts.
ERS Emergency Visor Release and a new Visor Extension to provide protection from roost and the sun.
New eject technology includes the eject helmet removal system.
Helmet composition:
20% POLYURETHANE, 17% POLYCHLOROPRENE, 16% CARBON FIBER, 14% FIBERGLASS, 12% POLYSTYRENE (EPS), 7% ARAMID FIBER, 7% POLYAMIDE, 4% POLYVINIL CHLORIDE, 2% STEEL and 1% EXPANDED POLYPROPYLENE
Protection:
The helmet’s shell construction utilizes a highly advanced molding technology with a multi-composite combination:
3K Carbon, high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell
Uni-directional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy
Aramid fiber layer which provides critical penetration protection
This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the 4 density EPS liner.
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.
