This is a very nice string bikini from Calvin Klein. The fabric is soft, smooth, and stretchy which accomadstes the Male anatomy well. The front is small due to the string bikini cut, but is very wearable all day. The back stays put well. Sizing was a bit different in this though. I am a mens medium which is typically a womens large. I initially ordered a single large bikini, but it was actually too big in the waist. The string waist band was a bit loose because it is very stretchy, which alleviates it from cutting in. However, I re-ordered the 3 pack in a medium and they fit perfectly!
