Polarlens S26 / Cycling Glasses / Sport Glasses / Running Glasses / Exchange System Lenses /German Engineered / Introductory Pricing for US market / Includes belt loop carrying case and microfiber cloth bag for cleaning These are new on the US Market from our German partners. You won't find too many new looks like this at this price. Our buyers are impressed with the quality of the exchange lenses and are eager to use them in different weather. A beginner may have some trouble learning how to use the exchange lense but once you get the hang of it they exchange quickly and smoothly. This is like 3 glasses in one. I would not recommend these for the very large face. The frame has a cool two tone (silver/red) design. You will surely be happy with this model. Our exchange glasses are priced to sell affordably in the US as we work directly with the manufacturer. Happy sporting!
