This sports belt is a combination of PU material on the front and polyester lining, which is thick and tight, making it one of the more comfortable sports belts on the market. The belt is 18.5cm wide at its widest point to match your body’s natural shape, which is lightweight and highly durable, and the D-ring allows it to have a higher load capacity, allowing you to connect relevant equipment to this D-ring for easy resistance or agility training.
