The listing, Men's King Size 4x Lounge Shorts - EUC has ended.
I bought these for my dad, who normally wears a size 4X off the shelf at normal retail stores. He wears a 44 waist on his jeans. He put these on, and they just about fell off him. After a washing, they still seemed too big. The tape measure just across the waist from one side to the other is 22", so I am going to assume that they would be about 46" around (so not that big), but the website shows they would fit someone who is about a 50". They have a drawstring and side pockets, as well as a button pocket on the butt. Worn a few times last week, then washed. I bought him a 2X, which is more his size (and now he struts around like he's a much tinier man...so cute!).
