I had been searching for a decent pair of new ski goggles which would give me fog free unrestricted vision. I found what I was looking for in these Oakley Proven Goggles. The dual vent and persimmon colored lens has enabled me to ski longer and through blizzard type conditions on the ski hills in Upper Michigan. The only downside is that this style will fit smaller faces comfortably. That was no problem for me but may pose a problem for "shooshers" who have larger "noodles" or wear glasses.
