The all-new SM5 helmet is the result of more than five years of intensive study, development and testing. Based on Alpinestars’ five decades of protection development, we scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort.
KEY FEATURES:
HIPRO HIGH IMPACT POLYMER PARAMETRIC SHELL:
A polymer blend enhanced by varying degrees of thickness engineered to deliver the optimal combination of impact protection and light weight
5 DENSITY EPS LINER:
The right density in the right area for enhanced impact absorption
INTEGRATED COLLARBONE PROTECTION:
Features an engineered raised area with padding to effectively reduce the forces transmitted to the collarbone
PATENTED VISOR RELEASE SYSTEM:
Allows visor to release in a crash with the correct pre-determined amount of force regardless of angle of impact
OBLIQUE IMPACT PROTECTION:
Inner and outer surfaces engineered to minimize effects of oblique impact
ULTRA-VENTILATED DESIGN:
Visor directs air into ports for enhanced airflow
LIGHTWEIGHT CONSTRUCTION:
A size Medium weighs 1260g (ECE)
ERS EMERGENCY RELEASE SYSTEM:
Permits the safe and easy removal of the cheek pads while the helmet is still on
HYDRATION COMPATIBILITY:
Integrated cheek pad loops hold hydration hose
26MM WIDE CHIN STRAP:
The strap is wider than certification requirements for safety and rider comfort
