Just got back from 10 days @ Whistler and these goggles were amazing. Started out with bluebird conditions, which the black ignitor mirror was perfect for, then the warm front came in with powder/heavy snow in the alpine and spring skiing/rain below mid-mountain with periods of dense white out conditions. I easily swapped out the lens for the red sensor mirror and the visibility was near perfect...never fogging up once! I cannot say how happy I am with this purchase and feel I truly put these goggles through the ringer with just about every weather condition possible.
