This is literally the first review I've ever written- loved these so much that I wanted to share my thoughts. Super easy to switch out lenses; had to do a couple times on the trip and was impressed every time. Field of view is exceptional and crisp; also really easy to clean. I have a wide face and a square jaw line, and I think I rocked 'em. Hubby got the I/OX's and also loved them. Much bigger than the I/OSs- I tried his on and they were def too large for my face. Now I need to change out my helmet as I didn't love how it looked with the goggles; it was time anyway!
