Slim, simple, good. The Defey in the half-frame version is particularly well suited for slim faces. The range of use, on the other hand, is broad: Hiking, cycling, water sports, eating ice cream, the Defey is there. Soft temple tips and nose pads guarantee comfortable wear and a firm fit for all activities. The mirrored lenses of the goggles reflect infrared rays, provide 100% UV protection and offer a tint from Cat. 1 to Cat. 3 depending on the lens version. One thing is certain: the eye.
