Not bad....i guess. I was truly disappointed in oakleys quality with these goggles. they worked great for about 3 days and then for some reason they slowly began to get foggier and foggier. soon they were so foggy i could not see 4 feet in front of my face. I tried to wipe the fog of with the bag, thinking it was on the outside of my gogg's but it turns out that a seal or something broke inbetween the inner and outer lens and it is impossible to wipe the fog out. oakley not your best, considering i own 5+ pairs of oakley googles and sunglasses i would know these do not meet my expectations for oakley. they do not even come close to sort of meeting my expectations.
