Collarbone protection
The bottom profile of the helmet is sculpted to
clear the rider’s collarbone while the section
of the base pad immediately above this area is
made of a flexible compound rubber section
to further lessen the impact of any likely
connection between helmet and collarbone in a
crash. Further protection is afforded by the use
of polypropylene on the inner chin bar, which
allows a degree of lateral protection.
Post-crash safety
In the event you do go for a big one, the
S-M10 comes with ERS (so many acronyms!)
– Emergency Release System – which allows
the cheek pads to be removed by medical
staff prior to removing the helmet. But to help
further, the S-M10 is also ‘Eject’ compliant,
allowing the Eject inflatable emergency removal
system to be deployed – which is critical in
spinal injury situations.
Extreme comfort
Using heat mapping tests Alpinestars has
worked hard on the ventilation system to
optimise the flow of (hopefully) cooling air
around the rider’s head through the provision
of multiple intake and exhaust ducts (guarded
by wire gauze). This combined with a Cool-
