Alpinestars Helm S-M3 White

Advanced Shell Construction: This helmet
features a thermo-injected shell incorporating a special polymer blend enhanced
by varying degrees of thickness that is engineered to deliver the optimal
combination of impact protection and lightweight. The SM3 medium weighs 1430g
(ECE) and 1460g (DOT).

Ventilation: Maximized ventilation and high
levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.

Rotational Acceleration Force Protection:
Alpinestars patented low-friction coating is applied to the inner part of the
main EPS liner to reduce the rotational acceleration forces that can result
from certain oblique impacts. This layer essentially acts as a slip plane to
mimic the brain’s own low-friction cerebrospinal fluid, which is the body’s
natural defense against oblique impacts.

Visor Release: Patented visor release
system ensures the visor is released with the correct pre-determined amount of
force, effectively reducing the forces on the rider’s neck during an impact.

The inner and outer surfaces are engineered
to minimize the effects of oblique impacts.

5 EPS inner parts with 4 densities to
effectively manage volume and impact perfromance.

Hydration tube channels are integrated into
the helmet’s cheek pads for convenience and performance.

Comfort liner is constructed using recycled
materials for a lower carbon footprint.

The fit can be tailored to the rider’s head
thanks to the helmet’s crown and cheek pads, which are available as genuine
spare parts in different thicknesses.

Alpinestars has introduced a new in-house
standard for the SM3 helmet to test the helmet’s chin to conditions heavier
than the homologation standard, and in order to pass the Alpinestars’ new
standards, the shell thickness and the structure of the helmet design itself
have both been optimized on the chin area for superior impact performance.

The inner and outer surfaces are engineered
to minimize the effects of oblique impacts.

Equipped with an Emergency Release System
and removable cheek pads to permit the safe and easy removal of the cheek pads
while the helmet is still on, while the 3D contoured foam ensures rider
comfort.

Soft textile chin strap is 25mm for optimal
safety and rider comfort.

Stainless steel D-rings ensure a tight and
secure fit.
