I have the Koko pattern and just order this one as well as the blocks... I love these because they give you more feel in the water and not quite a revealing as a full brief, as I am still a bit bigger (size 36 down from 40) I wouldn''t feel comfortable in a euro brief with my butt hanging out. I swim everyday, and they are great; no fade, and fit great.

And I have to disagree with the previous review, he either order a female version, which there is one, or he insists on showing off his package because it is on the small side.

So this is totally a personal preference kind of thing and you''ll either agree or not, but it should be helpful either way!  My only complaint about these is in the ''pouch'' area.  These aren''t really cut for a man''s profile and as a result they tend to really flatten things out in the crotch.  Maybe that''s just what you want in a suit (minimize your manhood), but I prefer it to have a little extra contour there, creating some definition.  The photo is a bit misleading in this regard.
