Alpinestars SM3 Radium 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 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
- ttPatented visor release system ensures the visor is released with the correct predetermined amount of force
- ttEffectively 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
- ttAlpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces
- ttActs as a slip plane to mimic the brain’s own low-friction cerebrospinal fluid
- ttReduces forces of oblique impacts
Equipped with an Emergency Release Cheek Pad System
- ttPermits 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 certified
