Unique manufacturing, protection first

The all-new SM5 helmet is the result of more than five years of intensive research, development and testing. Based on Alpinestars' five decades of protection development, we have examined every possible aspect to construct a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort.
