The Peu à beauté cotton waist trainer is designed to gently shape the waist area while supporting natural thermoregulation thanks to the innovative CI Fiber technology. The special Power Net fabric with CI fiber uses body heat to emit infrared radiation, contributing to better circulation, muscle relaxation and harmonization of the circadian rhythm. The surface layer contains shea butter and other natural ingredients for gentle skin care. The belt is made in Japan from premium Japanese materials and is suitable for both women and men.
