And it can be reused after small crashes as the liner material “bounces back”.
The Koroyd liner has been used in bicycle helmets.
Now American company Klim features the material in their F5 adventure helmet. It adds about 40% to the price.
Australia currently only gets the Klim Krios adventure helmet ($A750-$950). There is no word yet on whether the F5 with Koroyd will be coming here, but it is being Euro approved which means it would be legal.

While EPS is the industry standard in helmet lining, there are other helmet inventions that also claim to be cooler and increase impact absorption.
