I purchased the one for sunny day , that's what it was written on its site. Well, i bought that one and i think i have used thrice by now. The viewing is good and clear, it covers most of the areas so i get the clear picture of where i am going and if there is any obstacles are on the way or not.
The glasses are anti fog so i don't need to clean it again and again. It's also safe because i always get the clean image without getting the blurry vision. The ski goggles are easy in wearing, with a helmet it is much compatible and without hurting my head i can wear it for a long time
