They are excellent with one exception. They seem a bit loose and have a tendency to fall forward off the bridge of my nose. I did order the largest size and that probably makes it my fault, but I'm known to have a big head...size 7 3/8 hat size. I lose my sunglasses several times a year. I want to have polarized and I don't want the cheap roadside variety. I had been going to a sporting goods chain store and paying @$25 each time I lost a pair. These are nearly as functional and certainly more attractive. For under $6 each they are a steal.
