I just finished a 4 day, 110 mile white water raft trip on the John Day River in the high desert of central Oregon and I wore these glasses the entire time. They are light, durable and fit perfectly. The lenses enhanced the colors of the landscape and brought out highlights of features that would have otherwise been unrecognizable. Everything just looked more vivid. I had other ‘designer’ brand glasses that cost 3-4x but didn’t even bring out because I enjoyed the Rogues so much. I’m excited to try these mountain biking and skiing. I’ll be purchasing more soon!
