Great looking frames August 28, 2017
Reviewer: Jason from N/A  
These frames are my favorite of all the sunglasses I own. They fit my big head perfectly. They are extra large lense that give lots of visibility. My eyes aren't tired at the end of the day from having to squint in the sun all day fishing.
