As a cancer patient, I was taking steroids along with cancer medication, so I gained an extra 45 pounds thanks to steroids! This harness offers a comfortable fit and also stretches when you sit down! The extra flex in the middle makes this belt a great buy! By the way. After 3 years of chemotherapy and radiation I'm in remission! I hope I can shed those extra pounds and have even more fun wearing this belt! You can easily adjust it to any size!
