The S-M10? design is coherent to Alpinestars
philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive,
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 construction. The surface curvature
promotes reduced friction on impact, allowing
deflection and the most efficient transfer of energy
to protect the rider? head from direct force to the
skull and referred to the neck and spinal column.
The aperture is designed to accommodate a wide
variety of goggles and the air vents in the shell are
located to maximize ventilation efficiency.
The S-M10 shell has been profiled with\performance as a priority and with a design style
that identifies the profile of the helmet and its
sculpted surface as uniquely ?lpinestars?
Another key feature is the S-M10 shell sizing
solution; each helmet fit size has its own appropriate
shell size to deliver the most anatomical solution
for the wide variety of fit needs worldwide.
The helmet? 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 EPS liner.

The result of the unique shell lay-up process
employed in the S-M10 construction results in
extremely effective impact protection. With a fully
equipped helmet testing facility, within Alpinestars
Racing Development Center, an exhaustive impact
research program has resulted in the S-M10
returning linear and oblique impact performance
which far improves upon current helmet regulation
standard limits. For direct, linear, impact by an average
magnitude of 41% and for rotational acceleration,
oblique, impact performance by an average of 48%.
