My husband bought this, but he only tried it on once, so there's no sweat or smell. It's practically new. The shape is slightly bent due to the packaging when it first arrived, but it should conform with use. A high-quality cowhide power belt that provides strong support during training. - Back Pad: 7mm EVA and cowhide - Size: M - Waist: 75-100 cm - Width: 11cm (max) - Total Length: 110cm (M) Thank you for looking.
