I have a pair of Serengeti Cavalin's. They rock....however the lens popped out one day and shattered....its like 60/70 bucks to replace. So i bought a pair of Maui Jim MJ Sports. I found them more comfortable then my cavalin's but they are polarized...they worked on the lear 60 i was flying...not sure about the CRJ. it is the same avionics package so i'll find out when i get on the line.
