two-piece singlets? in High School Wrestling Posted July 21, 2011 · Report reply Good article. Notice that two of our sports best marketers, Rob Koll and Tom Ryan, immediately jumped on board because they understand the ramifications of the singlet. To me this is a no brainer. I do agree that rash guards and board shorts are even better. Are mma guys constantly getting their fingers injured? It doesn't seem like it to me.
