These are an updated version of goggles i wore years before. The goggles are of two parts, eye piece and straps. The eye piece is spot on, nice fit on my face, decent anti-fog, good field of vision. The straps are excellent quality, with a good adjustment fittings; but the double strap at the back of the head doesn't split very far apart, which i personally don't like but this is more of an individual issue. This isn't a big enough issue for me to not wear them though.
