The venting system to keep both your glasses and the lenses on this goggles depends on movement of air which is greater when downhill sking but not so predictable when alpine sking.
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.
