Thanks for the info, singletlover. What model(s) do you have?
Jerry,
Japan Swimsuit Shop sells them, as does Mizugi on
Global Rakuten.
Tomsports Japan also has a range of brands from Mizuno, Speedo, and even Tyr. It seems they are out of the Asics, though. I haven't gotten a reply back as to when they will restock their Asics swim briefs.
