These goggles fit my face nicely, I found that they are fairly resistant to scratching bit as with all goggles you must be careful. The lenses did not fog up to often until after many uses when I figure the anti fog coating was probably beginning to wear away. The nose and the foam of the goggle is comfortable on the face.
The venting system in them is not the best and could have used larger vents for quicker cooling. The optics were good in these goggles but I have been much happier with other brands as well as other models from Smith.
If you want better optics in a goggle check out Oakley.
