The title says it all. Even though I've only been wearing this belt for a week at work, I'm already thrilled. I work very actively outdoors, bending, squatting, stretching, kneeling, etc. And for the first time in the distant past that I can remember, I've gone through a 6-day work week and never once stopped adjusting my belts. Time will tell how well he supports this claim. For now . with zero point adjustment, high-quality materials and at an amazingly low price. I am very comfortable. I just ordered another one.
