Okay guys, just ordered a Titan Singlet, size LARGE, which is supposed to be for 149 - 181 lbs and I am currently 164 lbs. The problem with it was that it was just too tight on my groins and ham strings which made it feel uncomfortable. Does anyone have any recommendations for to get a singlet that is not super tight and is like really stretchy so that I don't get that constricted feeling? Really appreciate it!
