For those who have a large tummy, this is a god send. One of the most common problems I have is that it’s very hard to keep the pants in place. as I walk throughout the day, the pants will slowly slide down. it slides down a lot more than a normal person because there is a slope that pushes down the pants with every step.
This is one of the stretchable belts in the market I found. haven’t yet found any better. It stretches so you can adjust it to be tighter or looser depending on what you are wearing, whether you are full or not etc.
or you could consider using suspenders. I never thought I might need this.
