Hello we are very sorry about the confusion it contains measurements in "catties," which is a unit of weight used in some Asian countries, especially China. One catty is approximately equal to 0.5 kilograms or 1.1 pounds. Here's how to interpret the description: "[140-180 catties] can be worn" means that the towel is suitable for individuals weighing between 140 and 180 catties, which is roughly between 70 kg 154 lbs and 90 kg 198 lbs. [80-140 catties] can be worn" means that the towel is suitable for individuals weighing between 80 and 140 catties, which is roughly between 40 kg 88 lbs and 70 kg 154 lbs.suitable for individuals weighing between 80 and 140 catties, which is roughly between 40 kg 88 lbs and 70 kg 154 lbs These weight ranges suggest that the towel is designed to accommodate a variety of body sizes and can be comfortably used by people within the specified weight ranges.
