Query: Bobster Sport And Street Goggles/Sunglasses Black BSSA001AC

The glasses are great; they're exactly what I was looking for. I bought these as a birthday present. The convenience of having one pair of glasses for motorcycle riding greatly appealed to me. Forget carrying extra, bulky glasses! You only need to carry the lenses to change out when needed. They have a great fit and look good. The case is nice too. There's nothing negative that I can say. Thanks!
