“I purchased the Siroko K3s Zurich Sport Sunglasses and am very pleased with my purchase. The K3s are just incredibly lightweight and very comfortable. Primarily I use the K3s for cycling.
Pros:
* These sport sunglasses are very comfortable (see caveat, below)
* The quality of the material is very good
* There is incredible venting. The only times the glasses started to fog *slightly* was when I was wearing a winter face mask in the cold and breathing up into the glasses. Otherwise, the air circulation in these glasses is incredible.
Cons:
The only complaint I have with these glasses really isn't about the glasses. When I'm riding I tend to grimace, and the lense rubs on my face. Once I relax my face I don't even notice the glasses.
If you're looking for a pair of high quality, reasonably priced sport sunglasses I'd say these are a sure bet.”
