Smith 4D Mag
You can now see more than ever before. The all new 4D MAG™ raises the bar for lens innovation with the introduction of BirdsEye Vision. This state of the art lens technology has a 25% increase of overall field of view compared to the I/O MAG™. In addition we have evolved Smith MAG by integrating the dual locking mechanisms into the goggle frame outriggers to make a quick and easy lens change system. We know that with BirdsEye Vision featuring ChromaPop lens technology, you'll be able to see even more detail as you take on untracked territory.
