This is big enough to fit my 40" waist, although I attach it on the side so the cut is along my leg instead of at my crotch.

It's possibly a tad longer than what I prefer, as I don't like towel wraps (or shorts, for that matter) to be long enough to hit my calves when I walk or are long enough to touch my knees. (I know, most shorts are super long nowadays.  I am 5'11" tall, so I'm not short, either.)

I like the quality of the product, no complaints there.  And the color is a dark black, which is good.

Overall, it's very nice, and I would buy another one.
