Worked like a charm on my recent trip to CO.
- The fit nicely with a helmet on
- Gave great range of sight.
- Changing lenses is super easy.
- Fogged up just a tiny bit on a really warm day when I was drenched....but not as bad as my other pair
I would recommend to others and purchase again. I think everyone on my trip wants a pair now after letting them try them out for a while.
