Have only just seen the Mategear brand. I think the designs are really hot but realistically, I think that they are only designed for the Asian market. I love low cut swimwear - I am a great fan of NeptuneScepter and wear them whenever I am swimming laps in the pool as well as on the beach - but the Mategear briefs , and especially the bikini briefs, are so low cut at the front that I cannot imagine how mens tackle can possibly be squeezed in, let alone be made decent in a public place and the backs hardly cover any of the buttocks. Also the pubic hair has to be completely shaved.

Now I know how some of the Japanese boys get those incredible tan lines that go across the middle (or the lower portion) of the buttocks!
Incidently, I read that the guy who started, and designs for Mategear did his degree and training in England (The Northumbria University School of Design). Does that say something for British swimwear design?
