I use dragon DX with gold ionized lenses, and those are some really good lenses. They work in all conditions, and they never fog up. The only time they fog is when you come inside from a cold day, and you get the fog on the outside, but that happens on every goggle. Once you start to move, any fog that might be in the lenses will just go away. Your vision is kinda limited, but i don't mind it at all. The gold ionized are definitely the lenses you should go for if you get the DX's.
