The description for this product was exactly what I needed. It relieves the muscle fatigue I experience in my back, possibly due to bad posture, and also helps to improve my posture when I sit, stand or walk. When I first saw the belt I had my doubts about how comfortable it would be. I do wear my belt over a light top and I am able to wear it all day. I am delighted with the difference it has made and it is very reasonably priced.
