I used 24/7s many years ago and had similar issues with the leg gathers. Those and a couple other brands just have a weird cut the way they are made that doesn't fit my body well. Northshore Megamaz has been hands down the best product for me. Bulky but if you only need at night they are pretty close to perfect.
Most everybody has a favorite product for sure but no matter who makes the product if the leg gathers don't do their job then the diaper is completely useless as far as I'm concerned. Without good leg gathers you have nothing!!!!!
