"The name may not be up with the likes of Oakley, but don't ignore these Madisons"
The name may not be up with the likes of Oakley, but don't ignore these Madisons. The Carl Zeiss lenses are unparalleled for the money- they really are excellent. They're well vented, making them some of the quickest here to clear fog. The lens depth is reasonable, but the non-adjustable nose-piece means they sit quite high if you've got a wider nose. Popping the lens out of the frame is easy, but replacing them does requires a knack, as seating them seems tricky at first. The frames are made from a reasonably stiff plastic, with little flex in the arms. But this lack of flex doesn't cause any discomfort if they fit, and they're certainly worth considering if you've got a slightly narrower head.
