The glasses fits perfectly and seals excellently from. Actually a smooth 5-star glasses. Unfortunately, the nose bridge is structurally a vulnerability. With me went to the imprint on the gum and the two glasses only hung on 2 thin rubber bands, making the glasses would also leaking. Although I have never turned to web and the glasses have plugged immediately after swimming in a box just kept times a year of web, where no I swim in the summer. I probiers again with a Zoggs - if it again so I'll take a completed another brand
