They are comfortable enough to be worn all day. Foam "gasket" for the face fits very well. The lens is the sharpest I've ever had. Looking at them, it looks like they forgot to put lenses in. Fog lights work well until you are in a hot, humid environment. They have an oily appearance when viewed through a lens. In fact, it doesn't fog up at all and maintains useful vision even when others fog up until they block vision. I've had "anti-fog" face seal lenses before, although they didn't even work that well, so they should work pretty well until someone comes out with "anti-fog" lenses.
