Julbo Drus Matt Black Sunglasses, Leather Side Shields, Cat. 4 Lens

You have to be aware that the design of these sunglasses has an inclination type of frame, in some occasions produces a reflex effect that is unpleasant.

Good sunglasses for posing in the Zermatt cafe :) Actually I gave them to an online optician and got prescription lenses put in them. They then avoid wearing a helmet visor when skiing. The leather side bits stop your eyes running.Update: the leather side bits are attached with flimsy plastic clips which get damaged easily. Once this happens, the sunglasses are just normal cheap sunglasses.
