Mike, the DJs Speedos would be genuine. Just poor quality made in China is what we get here now. Bad design too. I find them too loose at the back and very narrow in the front.
TYR Durafast swimwear is sold through some public pools. Waves pool near Southland sells them.

They also have a new brand there called FINZ.
Good luck.
