This is a brand new, unopened item. Brand: #BAMBIWATER Material Composition: [Body] Nylon: 92%, Polyurethane: 8% Care Instructions: Machine Wash Size: M Color: Black [Full coverage for your abdomen! Heat shorts that warm you up with just one piece] Super high-waist design that covers the entire waistline. It covers a wide area, especially around the navel and lower back, which are prone to feeling cold, providing a sense of security and warmth, as if you were wearing a belly band. [Comfortable anytime, at home or when going out, thanks to the moderate thickness] While not feeling the tightness typical of high-waist designs, it wraps around the lower abdomen and hips, providing warmth that lasts all day. The moderate thickness doesn't interfere with the silhouette of your clothes, and it's comfortable to wear for long hours of desk work or standing, without digging in. [Uses fabric with excellent heat retention due to far-infrared processing] The fabric is treated with far-infrared processing, which absorbs far-infrared rays emitted from the fabric into water molecules, causing the molecules in the body to vibrate and generate heat. The warmth lasts, and you can feel a gentle warmth from the inside out, not just on the surface of your body. *Due to the strong corrective power, if you are concerned about the tightness, we recommend going one size larger.
