The fit is "magical!" I've had 3 or 4 of these goggles and the main reason I've gone through so many is that the antifog, at least for me, is worthless. So I've used all kinds of antifog stuff, which inevitably scratches my lenses after applying and using my finger to make sure it is coated. I finally found a great antifog spray that works for me! I spray it on, let it dry (I don't touch it) and then when I'm ready to swim, I rinse the goggles in the water...and voila! No more fogging, even after 40 min or more! I love these goggles for my triathlon training and racing. I would give a 5 if the original antifog worked at all.
