This wide belt, 22cm in width, provides firm support for the lower back with two elastic belts and four plastic stays. I only tried it on. I couldn't use it because the size was too small. Perhaps because it's unisex, the size is L~LL, but it runs small. I think it would be suitable for those with a waist size of around 70-75cm. Size: Height 22cm (at the widest point), Width 95cm Thank you.
