This goggle, like its other smith counterparts, never fogs up. Its sleek design make for a very stylish and easy functioning google. I've used both the I/O and the I/OX in the past and this is the perfect in-between goggle. Not too large but not too small. It fits very fell with a helmet whether the straps are over or under. The lenses are relatively easy to change and come in all sorts of color verities. The goggle sits very well on my face, which I would say is average size(L smith MAZE helmet), there are no pressure points, only comfort. This is my all time favorite goggle and I would recommend it to anyone!
