Period Underwear

Period underwear is a reusable, lightweight undergarment designed to absorb menstrual flow, providing an alternative to traditional pads and tampons and expanding beyond periods to include light bladder leakage. The trend reflects growing interest in sustainable, comfortable, and convenient feminine care products, driven by consumer demand for inclusive, body safe solutions.
