Alpinestars Supertech M8 Radium Helmet

Years of experience designing and manufacturing innovative motorsports technology has given Alpinestars a mastery in outfitting racers, drivers and riders of all types. The Alpinestars Supertech S-M8 helmet was built from the ground up to be comfortable and protective while still offering high levels of performance for off-road riding and motocross. The Supertech S-M8 Helmet is constructed of a multi-composite shell and multi-density EPS polymer for for keeping impact energy from reaching your head. Multi-directional Impact Protection System (Mips) reduces slow glancing rotational impact energy that commonly causes concussions on off-road rides. Emergency release cheek pads along with the "Eject" inflation system allow for emergency removal of the helmet with less stress and movement on the spine.

Four shell sizes spread across the XS-2XL size range help keep a low profile and lightweight helmet that fits well. A micro-adjustable pad fine tunes the helmet tilt so you'll have the optimum view out of the eye port no matter what your riding style. Specially designed vents flow air into the helmet around your head to improve comfort when things heat up. Fit a hydration system tube into either side of the helmet to stay hydrated on your next enduro or casual ride.

The Alpinestars S-M8 Helmet is packed full or safety and comfort features, perfect for your single track ride or motocross race.
