The material is made of rubber and polyester, making it easy to use, soft, and fits snugly around your waist. It does not contain any support wires, so it is not stiff, and you don't have to worry about wires popping out even if you suddenly squat. The back is wider, making it easy to support your lower back. The one-touch Velcro allows for adjustable tightness and looseness. It's easy to fasten, so putting it on and taking it off is a breeze. It can be used in all aspects of daily life, including sports, long drives, handling heavy loads, and for those who stand for long periods. Although it is an unused item, please note that there may be folds, minor scratches, or dirt from the time of purchase. It will be folded and shipped in simple packaging.
