I know we've had a few discussions on here about sweating profusely and how to stop it. Well, nothing works for me. My armpits sweat a ton! I've tried just about every antiperspirant/deodorant out there to no avail. So, I've been thinking about wearing performance/compression tshirts under my shirts. My thinking is that it will at least keep the sweat close to my body and not soak into the shirt I'm wearing as easily. Regular cotton tshirts are loose and absorb the sweat and then soak the shirt it's under. Am I stupid for thinking this? Any suggestions on decent performance tshirts? I don't want to spend $30/each. Is there a good value out there?
