Smith's I / O is not only designed to be enable you to ski in style, but is especially designed to be able to respond quickly to changing situations. The I / O ski goggles have a system that allows you to quickly and easily change the lenses in case the weather changes. This allows you to immediately adapt your goggles to the circumstances. The goggles themselves also adapt to your face thanks to the Responsive Fit technology. The I / O goggles also have an average fit. The lens is spherical, for a wider field of vision, and is made using TLT technology, so you always get a crystal clear image. The I / O has an extra wide lens so that you can see even more during descents. The Porex filter ensures that the goggles adapt to the ambient pressure, so you also keep a clear picture when it really matters, for example with fast descents. The I/O MAG goggles also have AirEvac ventilation, which ensures that your lenses won't fog up with condensation. What's more, this model makes use of the MAG (magnetic) lens exchange system, so you can easily and quickly change the lenses. The reflective coating will help to reduce glare and to put less strain on your eyes. These goggles come with two different ChromaPop lenses; the ChromaPop Everyday and the ChromaPop Storm. The special ChromaPop lenses have the ability to filter light at two frequencies. The lenses are therefore suitable for a wider range of weather conditions. The ChromaPop Everyday lens allows a reasonable amount of light through and is therefore suitable for days with fairly average cloud and sunlight. The ChromaPop Storm lens is ideal in bad weather and cloudy days, as it transmits a lot of light. This combination of lenses allows you to enjoy perfect vision in almost every circumstance.
