The Smith I/O MAG XL has an impressive field of view despite their medium-sized frame. They worked great in a variety of lighting and weather conditions, and we really liked the ���slider lock� lens change system. It took a bit of getting used to���and practice to make it work on the first try���but once we got the hang of it, we loved the quickness of changing lenses. We loved the fact that you could not put the same pressure in the same spot during a faceplant, making the lens fly off. Our glasses-wearing testers also loved putting the goggles on without lenses, sliding their glasses in, then putting the lenses on.
