These things are so legit. First of all they are cheap so you could just buy a new pair if you scratch, loose, or break them. Second they are UV so they are good and protect you and not just tinted. Third the side flaps block out wind.
I just don't understand how people can pay $70+ for oakly or smith sun glasses. You guys are kooks!
I'm 5'10 180 lbs and I got a large. It fits good but it is way too short. The thmb holes are cool but too short so you can't use them with gloves becuase the cuff jams up. It's really nice and kept me warm all day snowboarding in 40-50 degrees on a windy day with just a T shirt on underneith but, it just has a few problems so I'm returing it. It'd be good if you just wanted it for climbing, but for skiing or boarding it sucks.
