Very easy to exchange lenses however the goggles were too large for my wife when using a ski helmet. The goggles forced the helmet to be pushed up high on her forehead. The same thing occurred with my adult daughters helmets.
Won't be using until vaca in December, so can't comment on anything but the way they look and fit. I love them, and can't wait to use them on the slopes. Also- the customer service I recv'd on these was awesome. Shipping was fast as well.
