i had low cost brand name goggles before i purchased these. what a difference especially with polarized lens. the other goggles use to hurt my eyes when the sun reflects off the icy snow but with these i can see clearly and the sun doesnt bother me too much. its best bang for bucks for polarized lens compared to oakleys. i gave a 4 star because the strap. although its easy to use it doesnt seem durable but well see.
