In the crotch area, we use a special design to stop side leaks. You can move, walk, or sit without worry.

Designed for Heavy Flow with Leak Protection
This period boxer is made to handle heavy menstrual flow, offering up to 40ml of absorbency, which is about the same as five regular tampons. It uses a multi-layer structure that quickly absorbs fluid and keeps it locked inside, helping you stay dry and fresh for up to 12 hours.
The top layer pulls moisture in within seconds, reducing wetness on the surface. Underneath, absorbent layers trap the liquid and prevent it from moving around. The bottom leak-proof layer stops any fluid from leaking through the fabric.
To further improve protection, the side leak barrier is built into the gusset area. It helps prevent side leaks when you're lying down, sitting, or moving. This feature is especially useful during sleep or long shifts.
The boxer brief style offers full coverage in both front and back, giving you a secure fit that stays in place without riding up or digging in. This makes it a reliable choice for everyday wear, night use, sports, travel, or postpartum recovery.
PFAS Free Period Underwear
PFAS are not just one chemical, but a big group of about 12,000 different chemicals. They stay in the body and the environment for a very long time because they break down very slowly. Some menstrual products use PFAS to help absorb more or to stop stains, like in period underwear. Even though there are safer materials that can do the same job, many companies don’t know they have PFAS in their products because these chemicals come from the raw materials they buy. We only use safe materials without PFAS. Our products still protect well against leaks, feel breathable, and are comfortable to wear. We test everything carefully to make sure our products are safe and good for your health. This is period care made with science and care for you.
Premium & Organic Fabric
Our period boxers are crafted using high-quality fabrics made from natural sources like organic cotton, bamboo, and modal. These materials are soft, breathable, and gentle on sensitive skin, making them ideal for daily use during menstruation. We focus on eco-conscious production, avoiding harmful chemicals to ensure safety and comfort. Each fabric is carefully tested for durability, moisture control, and skin-friendliness. Custom fabric selections are available to suit different market needs, helping brands offer sustainable and trusted products.
