Are Period Underwear Safe? Understanding the Facts

It is estimated that the average woman uses 9,120 tampons in her lifetime. To protect against leaks, women rely on various forms of period protection. Some prefer pads, tampons, menstrual cups, and other single-use period products, but have you ever wondered if there’s a reusable alternative? Meet the new MVP in your underwear drawer - leakproof period underwear. 

Leakproof period underwear is designed to look and feel like your basic underwear but made better. From buttery-soft materials to triple patented Leak-Loc® technology, our period underwear is well-loved and reliable. As with any protection products, you should learn how to maximize their effectiveness, care for them properly, and use them as directed. Luckily, when it comes to period underwear, they are rather simple to wear and care for. First, find your flow. For light flow days, consider our superlight or light absorbencies. For moderate flow, consider our moderate absorbencies. When the full flow arrives, turn to our heavy and superheavy, and overnight absorbencies for the protection you need. Next, wear them until it’s time for a fresh pair. Give them a quick rinse with cold water, and store in our mesh laundry bag. Our period underwear is machine-washable on a delicate cycle with cold water and gentle detergent.
