Alpinestars Supertech M3 Heat Helmet - Silver/Blue/Matte Black

Alpinestars S-M3 Heat Helmet

When it comes to dirt, the Supertech M3 Helmet is a value packed model engineered for MX, enduro, and recreational off-road riding. Whatever the terrain thrown at the Supertech M3 Helmet, the SM3 delivers where it counts most with DOT and ECE certifications that are paired with Alpinestars' 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. technology - helping to protect riders against brain injury from oblique impact. Four densities of EPS are used in every SM3, which employs five EPS sizes for a more tailored fit. 

Construction:

• Thermo-injected shell incorporating a special polymer blend
• Rotational Acceleration Force Protection
• Visor Release
• • Patented visor release system ensures the visor is released with the correct predetermined amount of force
  • Effectively reduces the forces on the rider’s neck during an impact
• 5 EPS inner liner sizes
• 4 densities of EPS effectively manage volume and impact performance
• Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance

Comfort:

• Fit can be tailored to the rider’s head replacement liner and cheek pads with different thicknesses (sold separately) 
• Maximized ventilation and high levels of heat transfer exchange
• 10 inlets and 7 exhaust ports
• 25mm soft textile chin strap

Safety:

• Rotational Acceleration Force Protection
  • Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner Expanded polystyrene (EPS) is a rigid, energy absorbing foam. In the helmet industry, EPS is the most common means of energy management to protect the brain. Generic EPS is often referred to as “Styrofoam” (a trademarked name owned by the Dow Chemical Company). Premium helmet producers utilize multi-density EPS liners to balance comfort, safety and performance. to reduce the rotational acceleration forces
  • Acts as a slip plane to mimic the brain’s own low-friction cerebrospinal fluid
  • Reduces forces of oblique impacts
• Equipped with an Emergency Release Cheek Pad System
  • Permits the safe and easy removal of the cheek pads while the helmet is still on
• Stainless steel D-rings
• Emergency Release System and removable cheek pads
• DOT and ECE 22.06 ECE 22.06 is a helmet safety rating that extends and increases the testing requirements of ECE 22.05 (with 22.05 being a more modern, more comprehensive European alternative to DOT). With 22.06, 12 additional impact points are analyzed (now totaling 18) and impact speed is increased (from 7.5 to 8.2 m/s). Unlike DOT, every ECE helmet model must actually be tested by an independent lab before it receives 22.06 certification.  certified
