Enjoyment and visibility for me can almost correlate directly. The ease of changing the lens, the versatile lens line up, peripheral vision, and anti fog tech add up to one impressive goggle.
I have put these through the wringer over the last two years and I am still loving my result. I am careful with the lenses, I do change them often based on conditions but heck that is why I bought them. I am firing for effect.
