My husband wears this everyday for work and man does it help, he works with stocking so constantly bending and lifting and this helps his bad back alot, without it he can't work. He is able to move in it with no problem, doesn't get in his way of working. Has plenty of stretch to it, so it can fit anyone, has 2 adjustable straps to it. Great product, Works very well, can't live without it.See full review
