Slipping a pair of Oakley's Wisdom Goggles on your face for the first time is a lot like slipping behind the wheel of a new luxury sports car or sport SUV--the universal descriptors revolve around eloquent terms like "wow" and "nice." The Oakley Wisdom Goggle might define the pinnacle of ski and snowboard fashion prestige, but the exceptional optical performance seals the deal for most discriminating and skeptical buyers. The second-nature fit is the result of a soft ergonomic frame and three-layer foam featuring progressively thicker densities for a plush and weather tight seal. The Oakley Wisdom Goggle has a curved lens that extends downward further than many goggle designs so you see more without moving your head. When aesthetics matter most, some buyers choose the sculpted and perforated lower vent construction found on Oakley's Wisdom Goggle over the foam insert vents on the Oakley A Frame, but what you may not know is that the vent holes on the Oakley Wisdom Goggles were specifically positioned to direct the airflow away from your eyes, which matters at altitudes where freezing temperatures and dry air can whither soft contacts into crystal raisins. The strap has a clean hinged attachment that won't interfere with most helmet designs, although Oakley does sell an articulated snap-on accessory strap for the Wisdom Goggle. One thing to keep in mind--Oakley designed their Wisdom Snow Goggles for medium to large faces. If you wear a small size helmet, you might be better served with the sizing of the Oakley A Frame Goggle.
