this is my second pair as i lost mine in Vienna. They are still terrific. Very lightweight, comfortable and durable.
Second pair of Rydon sunglasses. Love the interchangable lenses, love the prescription option, and mostly love the red and black transition lenses.
The Rudy Project Rydon glasses have a nice slim fit and work well with my motorcycle helmet not pressing the arms into the side of my head. The interchangeable lens give plenty of options for light conditions when driving.
