For pants that have lost their elasticity, this is exactly what you need. I fitted them snugly and snugly over the pants and the pants stayed on with no problems. I'm waiting for the belt to lengthen, but it doesn't seem to happen soon, and it can be adjusted to the place of knitting. I can still easily pull down my pants and belt and lift the belt without unbuckling it. Zinc makes it sporty in everyday life, but good enough for decoration. I might order another color in the near future.
