The Iris X Blue from POC is a double lensed ski goggle that provides great optical qualities and style. In principle, the Iris X will never steam up, even with major changes in humidity and temperature. These lenses also come with an anti-fog and anti-scratch treatment. The Clear/Red Mirror lens which comes with this Iris X is designed to have a contrasting effect with colors in the snow and sky. The result is a very versatile lens that works great from overcast to sunny conditions.
