Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement.

The Klim Krios Pro Arsenal Helmet upgrades the impact performance and ventilation with Koroyd materials and construction. When compressed, the Koroyd materials crush and decelerate the impact energy to reduce head trauma. A full carbon fiber shell with an unmistakable wide carbon weave cuts the weight while still providing a strong shell. A Pinlock-ready face shield along with a Transitions Photochromic lens are included so you can take on various light conditions.

The specially designed visor and spoiler help to stabilize the helmet at speed. A quarter turn release mechanism lets you swap out the face shield and visor quickly and securely so you can go from street configuration to off-road without any tools. Use the Klim Radius Goggles whenever you are running the helmet without the face shield for superb eye protection.
