Product Description

4 Layers Maternity Period Underwear for Mother

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.

Maternity Underwear with 12-Hour Leak Protection

This maternity period underwear is specially designed for women during pregnancy who need light leak support and full-day comfort. The soft over-bump style gently covers the growing belly and gives a smooth, secure fit without pressure. With a built-in absorbent layer, it helps manage small leaks from bladder pressure or discharge, which can happen as the body changes. The fabric is breathable and soft on the skin, keeping you dry and fresh throughout the day. Whether you’re resting, walking, or sleeping, this pregnancy period underwear provides gentle protection and ease of movement—making it a smart choice for daily wear. This over bump period underwear supports your body and helps you feel confident through every stage of pregnancy.

Designed for Heavy Flow with Leak Protection

This maternity period underwear provides high-capacity leak protection with a built-in core that holds up to 40ml of fluid. It’s made for bladder leaks or increased discharge during pregnancy. The multi-layer structure pulls in liquid quickly and locks it inside to help keep the surface dry. A special side barrier design helps stop leaks when lying down, sitting, or walking. The full-coverage boxer shape stays in place without rolling or shifting, offering reliable protection without extra bulk. This pregnancy period underwear is a smart choice for long days, travel, or any time you need leak support with comfort.

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 for Maternity

This maternity period underwear is made with skin-friendly fabric that feels soft and smooth, even on sensitive skin. It is free from harsh chemicals, fragrances, and dyes, making it safe for daily use during pregnancy. The material is OEKO-TEX® certified, meaning it meets high global standards for fabric safety. Breathable and gentle, it helps reduce skin irritation while keeping you comfortable throughout the day.

Gentle Fit, Pregnancy Cares

The soft waistband and flexible leg edges stretch gently around the body without slipping, digging in, or rolling up. The high-rise over-bump design offers full belly coverage and adjusts with your growing shape. Inside, the fabric includes a hidden layer that helps catch small leaks or extra discharge, common during pregnancy. The material is tag-free, smooth, and holds its shape after repeated washes. This pregnancy period underwear gives you a stable and gentle fit you can trust, with no tight spots and no fuss—just daily comfort and simple protection.

Still have Questions?

We have answers.

How do period panties work?

Our period panties absorb the flow, and keep you fresh, dry, and protected whenever you're wearing them.

- Anti-Odor & Anti-Humidity : The first two layers banish odors and wick away moisture from your skin to keep you fresh and dry all day (and night).

- Super Absorbent: The inner layer absorbs liquid and locks it in. Depending on the absorbency level you choose, they can absorb up to five regular tampons' worth of liquid.

- Leakproof: The leak resistant outer layer helps protect you from unwanted leaks, keeping your panties as spotless as can be.

Is there coverage in the front & back?

The absorbent area on most of our panties is located primarily within the crotch area, typically one to three inches from the waistband of the underwear depending on the style.

Each panties has a single layer of protection from the absorbent area towards the top of the waistband on front & back. There have a line of demarcation of the absorbent area and extra single lining of the underwear, feel free to contact us for more closely product pictures.

Are these washable?

Yep! Our period panties are machine-washable & reusable, so you can wear them again and again. It’s an eco-friendly product.

Simply rinse them in the sink, then hand wash with cold water or machine washing on a gentle cycle with cold water. Then hang up or lay flat to dry. Pls noted that just steer clear of fabric softener and bleach!

Can I wear them all day?

It depends! If your flow is heavy, we recommend changing them every four to six hours. However, you can definitely wear them for as long as you feel comfortable and under absorption level, especially overnight.

It's possible to wear them over than 12 hours, depending on how light or heavy your flow is. But wearing them for too long isn't something we recommend, since exposure to air might lead to bacteria growth.

Will I smell?

Make sure to care for it properly and wash it to keep things fresh, then no smell.

All of our panties have a thin layer of comfy, ultra-soft & anti-microbial fabric that removes sweat odor and eliminates bacteria to keep you fresh and odor-free. (It’s also have three other layers of fabric for ultimate comfort and protection!)

We have several pairs from Ecowoman and these are our favorites. They are super thin and don't look like we are wearing anything. They are cute and comfortable.

The best purchase lhave ever made. l bought them formy daughter, it was her first time with her period. l was able to make her feel comfortable and secure. I will definitely recommend them to others and will buy more from her in the future.
