Helmets have always been built to sacrifice their structure in order to protect the helmet wearer. But the conventional approach to absorb energy has always resulted in helmets that work like some kind of second skull, focusing their protection strategy on basic impacts that happen directly.

But Release Layer System (RLS) now know that it’s rotational forces generated by angled impacts that contribute to the stretching and shearing of brain tissue. RLS also know that doctors and scientists believe that this kind of damage is a primary cause of traumatic brain injury.
