The Oakley Wisdom G30 Goggles cloak your eyes in distortion free vision on all but the stormiest days. This goggle fits medium to large faces. Oakley's G30 lens increases contrast in blues and greens on the mountain—for days when lighting conditions vary to partly cloudy to overcast. Enjoy all-day comfort thanks to the Wisdom Goggles' triple-layer wicking polar fleece foam. Dual vented lenses keep these Oakleys fog-free for when you hike the pipe or slog up a ridgeline in February.
