Review on 👔 JASGOOD Canvas Elastic Keeper, 1.5-Inch, Top-Rated Men's Belts for Accessories by Domonic Roberts

This is a decent solution to the flapping belt problem. But they have a limited lifespan: they're basically just a loop of stretchy material that works great the first time you put it on, but over the course of a few weeks it will stretch and lose its support. As they come in a 5 pack for a relatively cheap price it's not too bad, but a more resilient stretch material would be an improvement.
