So I just bought a NIKE PRO COMBAT SHORTS and I'm wondering if it's alright to wear them without underwear and simething on top of it?
<laughing> Hey dude... it all depends on you.... They are intended to be compression shorts so they should fit really tight, and so no, you won't wear underwear under them. Wearing something over them depends on you: where you run, what kind of shape you are in, and who you run into. Me personally, I wear a pair of light shorts over my compression shorts. My junk is my junk... :-)
