I was looking for a new pair of cycling sunglasses that would use the same Rudy Rx insert that I've been using on an older pair of Magsters. An online chat with a Rudy representative allowed me to quickly get a list of compatible frames. I chose the Fotonyk for the full eye coverage. My Rx insert works well with the frame and the second generation Impact-X photochromatic lenses.
Not much to say about bumpers except I love the color, they fit perfectly on the lenses. Typical high RP quality.
