I don't know, maybe it's the same username, but I agree completely with MrG. When I used to wear tanks, my shirts would become noticeably soiled after some time. I also find it hard to believe that with a blue shirt those who don't wear any undershirt don't have the wet stain occasionally. I mean we all sweat, whether as a result of summer heat or stressful situations, no? Maybe it's just me; maybe I'm just a freakin' animal. Stains are largely a function of the the additives found in most deodorants. Look for an aluminum free product. Also, shirts should be laundered after each use.
