Leak-Proof Protection: The underwear features a multi-layer design to wick moisture away from the skin, absorb fluid, and a final waterproof layer to prevent leaks and stains on clothing or bed sheets. Comfort and Material: Typically made from a soft and breathable blend, such as cotton or modal, they are designed to be comfortable and reduce irritation often associated with disposable pads. Reusable and Eco-Friendly: They are washable and reusable, serving as a sustainable and cost-effective alternative to single-use disposable products like pads and tampons. Versatile Use: They can be worn alone on light-to-moderate flow days or as a reliable backup when using other products like tampons or menstrual cups on heavier days. Pocket Feature: Some designs, like the one pictured, include a front pocket where a heating pad or extra absorbent insert can be placed for added comfort or protection
