Optrel sets a new standard in headgear. It’s the only product worldwide which is adjustable in width, length and height to any form of head - 3-dimensional. That’s why we call it a perfect fit. What seemed to be impossible is solved by a genius construction,which for the first time at all uses a liner fit system.

This connects a twolayer construction with two stabilizers on forehead and backhead. Fits to every optrel helmet. And to any headsize from S to XL. The optrel IsoFit® is available from October 2020.
