These Kutting Weight Sauna Pants are made entirely of 1.5 mm SweatTech elastic neoprene material, which moves with your body during any type of workout. The all-black design, with its reflective black logo, will help you cut water weight for competition or shed fat for improved health and body image. These pants feature a black checkered mesh material in the crotch for added comfort, flexibility, and breathability. The pants have the same great heat enhancement effects as our original model, but with improved technology and style. These pants are essential to help you bring on a good sweat and burn more calories year-round.
