Review on Ultimate Protection with ProSPORT Wind-Proof Polarized Motorcycle Mountaineer by Keith Alvord

They replace a similar pair I had when I lived in Idaho, the lens size is a bit larger than I would like but not too big (1 7/8" x 2 3/4 ") , but I think it's mostly unavoidable with side guards, otherwise after they break they fit fine. The improved visual acuity was unexpected, and while the lenses are fairly dim, they seem to offer good vision in low light. (the sticker on the lens says 400 UV protection) I use them all the time and they don't fog up at all. Sure, they block your peripheral vision so sometimes you have to turn your head to see, but I've been riding motorcycles for long enough that it doesn't bother me. One thing I didn't like about the goggles was the piece of leather between the lenses and the attachment cord, which I removed and threw away and replaced the cord with real leather instead.
