Tried a pair on at a local store, but wanted a better price. After two other retailers couldn't get me the shooting package of the non-polarized version, I settled on the polarized version.
The glasses stay in place during my running and biking. I need to get some lighter tints now that it is getting dark so early. The only real issue I have is that my bike helmet strap and some of my hats make me shift the ear pieces into less than optimal positions.
Nice case and cleaning sock.
