I tried a sample of the pull on Depends today. This is size XL which is for up to 300 lbs and up to 64" hips. While my backside is relatively flat compared to the rest of me (I weigh 300 and my hips are 58") these pants do not come up to my waist in the back. If I adjust them so that they come up more in the back, then they want to roll down under my belly. I think they need to have a different length for the rise. At least another 3" would be preferable. I normally wear size 11 or 12 Just My Size cotton underwear. Perhaps the dimentions could be taken from those. Otherwise, I like them.
