The product description said nothing about the fabric being thin and stretchy, nothing like the Hanes T-shirts I've had in the past. You can almost see through them and the fabric stretches horizontally which makes them crawl all out of shape and position under a cotton shirt. Every time I put one on I like them less. Regrettably, after using them only two months, they are headed for the trash while I try to find a traditional cotton fabric T-shirt.
