Huh!, that's funny. Ditto on the Smith I/O goggles Condor. I'm literally buying a pair right now. Great style, cool looking, less frame = more field of vision, and 2 lens = only needing one pair of goggles.
The lens swap out on the I/O's is so easy, so slick, it's kinda sad no one ever built it before.
incoming.......DUCK !!!
