I'm 6ft 1in and about 215 pounds. Depending on the brand, I wear fog pants with a 34" to 36" waist. That's why I bought the 38" and it fits well with some room left. Now just to see how long it lasts. I recommend.
Pros
I bought this belt for my father in law and he loves it! Fits as expected.
Cons
Excellent belt but the color is wrong. It's not even remotely brown, but more of a very light shade of tan.
