Are you wearing the UA 'underwear' boyshort or some of their shorter compression workout shorts/baselayers as underwear? The boyshort legs rides up on me (horseback rider inner thighs) and is too high of a rise for a lot of my pants.

I also think that fabrics like that get smellier than natural fibers. Same with Nike Dri-Fit. (Talking about wearing them for workouts.. maybe they wouldn't be so bad in low-sweat situations with dress pants, but then I am from the deep south where there is no such thing ).
