The comfort flex waist is a plus. It is very comfortable. The part that is not a good fit is from the crotch to the waist. You can't pull the pants up high enough to sit on the waist correctly and yet give you room in the family jewel area. As you walk in them my experience is they droop/fall off your waist so you are having to constantly pull them up. I have had other jeans from the same brand and they fit perfect. They are a nice product yet I think they would be better id they allowed for more area in the lower crotch. I will be interested to follow other customer comments to see if the same issue is experienced.
