This is the best pair of sunglasses I have ever owned.  The polarized TNS lenses do an outstanding job of eliminating glare, even when looking in the direction of the sun.  The view through these glasses is crystal clear and like no other sunglasses I have ever tried.  They also fit my head well.  I must have a wider face than average because several other sunglasses I have owned have cracked while putting them on or while being active in them.  These fit just tight enough to not slip at all during activity but are loose enough to be very comfortable.  They come with a nice case and a nice cleaning cloth.  I also think they look cool.  In short, I love these sunglasses and definitely recommend them to others.
