I love all the products I've bought so far. They are the best
United StatesPants now stay in place.
I am in my mid 70s and have tried numerous gadgets to keep my pants from sliding down. This is the only product to stop the problem and it enhanced my appearance as well. The only reason i didn’t give it a top resting is that I believe they should have a fly.
