Super soft, stretchy, and breathable. Great for the gym or lounging around, but I actually bought them in dark heather grey to wear as undershirts under Old Navy's white Pro Tech Signature Dress Shirts. Sounds crazy, right? A dark shirt under a white dress shirt doesn't make sense... until it does. ...As a dude blessed with melanin, white undershirts leave a stark visual break when looking at a dress shirt's sleeve. It shows how thin the dress shirt actually is. Wearing a grey shirt that is close to your skin tone will actually blend with your skin tone under the dress shirt, tricking the eye and making everything look uniform with the same white. If you decide to go this route, grab a tall so ensure that they don't come untucked. #sweepstakes
