Just wanted to share my 2 cents on the Wiley X SG-1 (V-cut) goggles.
These glasses are the best I've ever owned. I use them both at home for riding my motorcycle and at work for law enforcement duties. They keep the wind, dust, etc. out of my eyes very effectively. They also function well as safety glasses on the range. If I happen to be riding my motorcycle after dark, it is simple to change the lenses to the clear ones that come with these glasses. Excellent value for the price.
