Sunshine Neoprene Combo Hot Shaper Slimming Belt and Pants for Men and Women (Black, XXL)

The size was not accurate, the material quality is also low grade. But I used this anyways and it serves the purpose. I won't say it's the best choice you'll find on Amazon but it's quite affordable and if you want to try sweat belt for the first time you can go for it. Just order 2x of your size to get it accurate.

Along with exercise it works good
