I agree this looks pretty darn cool.
People spend thousands of dollars on skis, boots, clothing, lift tickets. I think another $500 isn't going to break the bank for a ski enthusiast. I don't know about you, but I've never lost/broken a pair of goggles in my life. I wear a helmet which has a strap/clip that holds my goggles in. Not to mention, the helmet also pretty much secures the goggles in place on your face. Unless your helmet comes flying off, the goggles are gonna stay on the face. While skiing, I think it would be pretty hard to damage goggles as well. If your goggles get damaged on your face, it's probably the least of your worries. But if I did have a pair of these, I'd probably be pretty paranoid about damaging them or losing them while not skiing.
