Alpinestars S-M5 Rayon, motocross helmet
Article No.: 11064306
The Alpinestars SM5 helmet is the result of more than five years of intensive study, development and testing. Based on Alpinestars’ five decades of protection development, every possible aspect was scrutinized to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort.
Features
- An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact
- Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in two sizes
- The inner and outer surfaces are engineered to minimize the effects of oblique impacts
- Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
- Patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact
- Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports
- The visor has been designed to direct air into the ports for enhanced airflow

I bought it for my daughter and the fit is spot on, it feels safe and light and the look is great. And a good price. I wish it had \"Mips\" though, don´t think that would break the bank if they included it. Motoin is great with fast delivery.
