One of the better pairs of swim goggles I've owned.  I bought the tinted smoke gray color and they are quite heavily tinted but still fine for indoor swimming pools.  Although they are well constructed and fit very comfortably they're still very light.  I've kept the goggles in the case they came in when not using them and over the past 6 months they've remained scratch free.  The anti-fog protection still works fine despite everyday use in a saltwater pool.  I rinse them in fresh water after every use--no other special care.
