Years of experience and innovation have gone into the Alpinestars Supertech S-M8 helmet. 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.
Features:
- Lightweight multi-composite combination shell: uni-directional carbon composite with an aramid layer
- Shell layers with an epoxy resin bonding for limited outer shell deflection so that the energy spreads wider and is better absorbed by the EPS liner
- Four shell sizes
- Multi-density EPS polymer liner four section construction that allows for specific densities of polymer to be prepared for different zones around the helmet lining
- Patented A-Head fit system allows the M8 to be tuned exactly to the riders preference with a micro-adjustable pad that is connected to the inner shell
- Patented visor release system ensures the peak detaches from the helmet if subjected to a significant impact while maintaining shell integrity
- Base of the S-M8 has been sculpted for collarbone protection and includes an energy absorbing pad
- MIPS incorporated to reduce rotation motion energy with a low-friction slip layer between the comfort liner and the multi-density polymer energy absorption shell
- Emergency Release System cheek pads
- Designed to allow a helmet eject inflation system to be fitted into the inside crown of the shell (sold separately)
- Wide 26mm chin strap
- Visor designed to direct air flow along with intake and exhaust vents
- Hydration compatible
- Removable and washable Coolmax liner
- DOT and ECE certified
