I just picked up these goggles, and day 1 I tested the impact resistance of these suckers. I smacked my face on a rail. I saw the rail hit my eye, but I barely felt it, no black eye, no cuts, no contusion thankfully because I don't have a helmet. The headphones make quality sound. They are not bulky, but not the snuggest fit either. Having an extra lens is a plus, if you are like me and slam face first.
Bottom line: I'd recommend this package to a friend, and am glad I purchased these.
