Depends whether you want something which works or something which works but which has a fancy name. I found that a pair of standard Polaroid clip-ons did the business, and kept the gnats out, but you have to buy them in the summer, as all the pharmaceutical outlets believe that the sun goes indoors for the winter months.
That said, you could always go to a cycling web-site and buy something fashionable, which I'm told provides a better sex-life than the Polaroids.
But then if you're REALLY putting in the miles that's academic, as you won't be able to find it for its hydraulic function, let alone for sporting use,
:eek:
Quickly nurse - the screens!
