The Speedo Vanquishers, which I have always used in the past for racing, have a much better strap that doesn't loosen.
And now after wearing the Tyr Socket Rockets for several weeks in practice I would continue to give them a good review for reduced goggle marks as well as no leakage. They have worked much better than the Swedes, which always leaked on my smaller face. For now this is my answer to the raccoon eyes problem!
