Protection:

• Alpinestars has introduced a new in-house standard for the SM3 helmet to test the helmet’s chin to conditions heavier than the homologation standard, and in order to pass the Alpinestars’ new standards, the shell thickness and the structure of the helmet design itself have both been optimized on the chin area for superior impact performance.
• The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
• Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort.
• Soft textile chin strap is 25mm for optimal safety and rider comfort.
• Stainless steel D-rings ensure a tight and secure fit.
• The SM3 Helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide.
  

Construction:

• The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
• 6 EPS/EPP inner parts with 5 densities to effectively manage volume and impact perfromance.
• Hydration tube loops are integrated into the helmet’s cheek pads for convenience and performance.
• Comfort liner is constructed using recycled materials for a lower carbon footprint.
• The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as genuine spare parts in different thicknesses.
