Great Glasses for running/cycling
I wear these glasses for running and cycling and absolutely love them. I have an average sized head and have never had any issues with them slipping or falling off no matter how sweaty I am. I use the polarized gold iridium lenses no matter the time of day or amount of sunlight and have never had any visibility issues. Definitely not a budget item, but if you've got the money to spare you can't go wrong with these glasses.
