I would strongly reccomend not getting them. My mom had them last year and she went to put them over her helmet for only the 2nd time and the small plastic piece that holds the strap to the frame broke in half and now they are done for. I am trying to get them warrantied but idk if they will do it.
My Phenoms and my dads Prodigy's were use a ton last year and never broke. Buy Smith.
