These are the best goggles I have ever bought ! After years of swimming with goggles that are just about comfortable and maybe leak on and off I have finally found d some that seem to fit perfectly for a small face and don't need to suction your eye sockets and leave horrendous marks for rest of day . They are super comfortable and very easy to adjust . They don't start to steam up until about 50 length . They were such good value that even if they don't last that long I would buy them again and again because it's just brilliant to find comfortable goggles that don't give me a headache don't leak and don't steam up immediately . I'm also a contact lenses wearer so they have made swimming sessions stressless . Brilliant !
