where is this from?
 

what brand?

I know these two divers wore these to an international event as part of team USA. I am just wondering if the speedos were ever available for purchase?

The light blue suit has a central rear seam, speedo used this when they made paper Lycra but the Japanese seem to have adopted this style in recent times. More likely to be Arena than Speedo.
I can't see enough of the dark blue suit to comment.

Probably specially made for a team and unavailable to the public.

The diver facing us is David Boudia from the U.S. - gold medalist in London. I think a couple years ago the US diving suits were supplied by a Chinese company, called something like Linang or Lining or something like that?

Li-Ning
 

Li-Ning At one point they were the swim brief supplier to the US diving team, and Olympic hopeful divers such as Steele Johnson were wearing their suits.

The suits had (have) a distinct Asian cut, low in back. not quite as low as Aqux or Seobean, but definitely on that order.

I think the company got overextended and ran into financial difficulties. They tried to be an Asian version of Nike, but that is tough to do.
