UNDER ARMOUR HeatGear red undershirt. The size is listed as MD. I used to wear it as underwear when wearing sportswear. I rotated between multiple undershirts, so I don't think I wore this one very often. I no longer wear it, so I'd like to pass it on to someone who can use it. - Brand: Under Armour - Size: MD - Color: Red - Material: HeatGear Thank you for looking.
