ALPINESTARS HELMET SM5 BEAM BLK/GY/RD L

• Constructed from a special lightweight and impact
resistant thermo-injected polymer results in a significantly
lighter helmet with increased structural strength and
outer shell uniformity in two outer shell sizes
• Inner shell includes multi-density advanced EPS construction
for optimal impact absorption performance in three sizes
• Features two concepts for impact energy management
including a resin-coated inner shell surface that noticeably
improves impact resistance and reduces linear acceleration
values and an elastic joint to connect the helmet's inner shell
and comfort liner to move independently in a crash scenario
with an oblique impact, thereby spreading the energy forces
from an impact, reducing rotational acceleration
• Uses Alpinestars Emergency Release System (ERS) consisting
of removable cheek pads for safe, quick and easy
removal of the helmet by trained medical professionals/​
emergency responders in the event of a crash
• The ERS features easy to locate pull-tabs for rapid release of
the cheek pads, thus minimizing risk of additional injury
• Includes a multi-angle, quick-release visor system that is flush over
the helmet's shell to diminish the visor protrusion from the helmet
thereby enhancing safety, doesn't use screws used in the visor for
increased levels of safety and convenience to be easily adjusted
and allows for ease of detachment and reconnection from the
helmet in order to facilitate helmet cleaning and maintenance
• Designed to offer exceptional ventilation to prevent overheating
on warm track/​trail days, with the inner air network channeling
combining with the outer-shell's multi-air inlets and exhaust ports
for effective ventilation and high levels of heat transfer exchange
• Hydration tube compatible channels are intelligently integrated
into the helmet's cheek pads for convenience and performance
• DOT FMVSS218 and ECE 22.05 certified
