Other brands of this same item I have tried in the past had the same nagging problem. They fit well coming out of the wash and when you put them on, but after an hour of wear begin to stretch out and relax. The result is baggy/loose fitting boxers. I hate that!

Not so with the Calvin Klein Cotton Stretch. These briefs stay the same shape and size and fit snugly all day long and without stretching-out. They  have also lasted for about two years and are just now starting to separate at the waistband. This review is after re-ordering them.
