Junk support is ok, if I need more I can wear a strap.  My purpose in buying these was more as a comfortable rashguard which they do admirably.  Years of soccer, wrestling, and weight lifting have given me thunder thighs.  Get the thunder thighs, the junk, and a 10 mile run in sweaty GA going and the hardest part of the run isn't the hill, it's the abrasions that form all over the place.  Not anymore!
