I have owned several other brands of goggles and this one is my favorite. I actually returned the i/os for the regular size i/o because they fit better with my face gaurd in snowstorms. I love the trees and these saved my eyes from being literally poked out, I hit them on several branches sticking out (some very hard) and I only have a couple of scratches after a full season and I can't see them when I put the goggles on. I had the ignitor mirror lens which does great in low/flat light but during blue bird days I wish I had a darker lens. I think they should make more lens options available because I didn't even use the sensor lens it was too light and would be good for night boarding. If I could make my own package I would have got the ignitor mirror lens with the darker mirror lens.
