Introducing the Havoc Helios Photochromatic Goggle. These photochromic lenses feature a dynamic Visible Light Transmission (VLT) that changes automatically. They shift from a high VLT (clear or light tint, around 80%–87%) in low light to a low VLT (dark tint, around 12%–17%) under bright UV/sunlight. Havoc Helios is a premium, fully customizable goggle. Designed with a quick lens change system, leading in class 17mm compression foam, extra comfort, and a leading in class field of view.
