4 Layers Leakproof Period Underwear
We’re patented for a reason. Independently lab tested and scientifically proven to keep you dry, fresh and odour controlled.
01 Crotch Layer. No Side Leaks
In the crotch area, we use a special design to stop side leaks. You can move, walk, or sit without worry.
02 Absorbent Layer. Strong Absorptuon
The absorbent layer uses polyester, which can hold at least 45ml of liquid. That’s more than a regular pad.
03 Leakproof Layer. PFAS Free
We use TPU, a soft and safe waterproof material with no harmful chemicals. It keeps liquid inside but still lets air flow.
04 Outer Fabric. Soft & Eco
You can choose organic cotton or bamboo fiber for the main fabric. Both are soft, breathable, and good for the skin.
This absorbent period underwear is designed to provide gentle, reliable protection for a wide range of needs, including geriatrics, maternity, postpartum recovery, incontinence, and menstrual care. With comfort and absorbency at its core, it offers peace of mind and support during every stage of life.
Girls who just started their period. They need simple, leak-proof, and comfortable solutions, especially for school and sleep. Period underwear is a safe, reusable choice for beginners.
People who bleed a lot during periods. They need stronger protection, often for overnight use or daily comfort. High-absorbency period underwear helps reduce leaks and pad changes.
Mons after childbirth. They often experience light bleeding (lochia) for weeks. Period underwear offers soft, chemical-free comfort and saves on disposable pads.
People who care about the environment and their body. They avoid waste and chemicals in regular pads/tampons. Period underwear is reusable, breathable, and made from safe fabrics.
Up to 12 Hours Leakproof & Odor Absorbing
Menstrual panties can be worn safely for up to 12 hours with no health risks. They’re designed to be breathable and help prevent bacteria buildup, keeping you fresh and protected all day or night.
Just make sure to wash them after each use — wearing the same pair two days in a row without washing isn’t recommended. For heavier flows, change earlier if needed to avoid leaks.

Menstrual Underwear for Heavy Flow
Specially designed with a larger coverage area, making it reliable even on heavy days. You won’t need to worry about leaks or not enough absorption. After 100 rounds of testing, the underwear showed a 98.8% success rate in instant absorption, with no side leaks or overflow in any case. The absorption speed reaches the second level, quickly drawing moisture away. At the same time, the fast-drying feature improves the overall experience by keeping the skin dry and comfortable. This is truly leak proof underwear for women who want both protection and comfort throughout their cycle.
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.
