Pros: Too much to list
Cons: Haven't found one yet
One of the biggest problems I've always had with goggles was lens tint. Sometimes it's to dark for overcast or snowy days, sometimes it's too light for sunny days. But the Zeal SPPX cures this. I cannow have one goggle for all light conditions. The photochromic lens changes tint with the light. A huge advantage on the slopes. And then the lens is Polarized to cut down on the glare.
This is the only goggle I've used for 2 seasons. It was a little pricey, but it has been worth it. 5 stars in my book!
