It is a plain T-shirt and does its job well. I'm too lazy to properly air dry select t-shirts so I ordered a size up anticipating the shrinkage the product description warns about. However, after drying it on high heat, it didn't shrink much between first arriving and after the dryer. American Tall are probably right in warning people not to tumble dry it, but if you don't want to air dry a $10 shirt, ordering a size up will not ruin the fit FROM MY EXPERIENCE.
I’m always adding basic t-shirts to my wardrobe — these are great quality shirts at an affordable price and will continue to make it in my closet. After one wash, they fit perfectly.
