The SM5 BondĀ helmet is the result of more than five years of intensive study, development and testing. Alpinestars scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort. This lightweight helmet features a thermo injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS (Expanded Polystyrene) liner ensures the correct density in the correct area for enhanced impact absorption.

  • Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in two sizes
  • Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
  • Side shell coupled with soft EPS (Expanded Polystyrene)Ā foam prevents damage to collarbone in the event of a crash
  • Inner and outer surfaces are engineered to minimize the effects of oblique impacts
  • Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports
  • Visor has been designed to direct air into the ports for enhanced airflow
  • Patented visor release system ensures the visor is released with the correct predetermined amount of force, irrespective of the angle of impact
  • Emergency Release System (ERS) and removable cheek pads permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort
  • Removable comfort liner with SILVERPLUS treated anti-bacterial fabrics for excellent moisture wicking, effectively drawing perspiration away from the skin
  • Anti-microbial liner is removable and washable
  • Hydration tube channels are integrated into the helmet's cheek pads for convenience and performance
  • Soft textile chin strap is 26mm and is wider than certification requirements for optimal safety and rider comfort
  • Stainless steel D-rings to ensure a tight and secure fit
  • Meets or exceeds DOT and ECE standards
