My husband has a 38"-Waist, (which is a Size Large in the Size Chart on Amazon and on the Hanes package). Alas, they were too small; had to return for a Size XL, (which is stated as fitting a Size 40"-42"-Waist). So, go figure. For my husband, the L ran small. Once we got the XL, he loved them so much, he insisted I come back and order two more packages! They are a little stiff out of the package but, I guarantee, wash them once and they're as soft as can be. However, please be aware that the MATERIAL is not like T-Shirt material... more like just a plain Cotton, but woven in such a way as to retain their lightweight feel. My husband has had the T-Shirt type material in his Boxers for the last 15-years. Now that he's retired, he's wanting to change his Boxers, Socks, Slacks, Shirts... his whole wardrobe! He was very happy to rid himself of the heavier Boxers and get these Lightweight ones.
