Product Description

4 Layers of Period Underwear, It has Crotch Layer, Absorbent Layer, Leakproof Layer and Main Fabric.

4 Layers Period Swimwear for Women

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. 50+ UPF

You can choose organic cotton or bamboo fiber for the main fabric. Both are soft, breathable, and good for the skin.

Enjoy the Water Anytime with Period Swimwear

Period swimwear lets you enjoy swimming, surfing, spa time, and other water activities during your period without worry. It’s perfect for the beach, pool, hot springs, water parks, and even summer camp or swim classes. Designed with multi-layer leakproof protection, this swimwear absorbs light to medium flow and keeps you safe and dry, even in water. The outer layer looks and feels like regular swimwear, while the inner layers lock in liquid and prevent leaks. It’s a great choice for teens and adults who want freedom and comfort during their period. Breathable, reusable, and free from harmful chemicals like PFAS, period swimwear offers an eco-friendly and stress-free way to stay active every day of the month.

High Absorbent

Anti Leakage

Odor Control

Certified Organic

Up to 12 Hours Leakproof & Odor Absorbing

These plus size period swimwear products are designed for light to moderate flow, giving you peace of mind while swimming at the beach, pool, or spa. The built-in absorbent zone offers extended front and back coverage to help catch light leaks when entering or exiting the water. The breathable, antibacterial lining helps reduce odor and supports all-day freshness outside the water. Made for curvier bodies, the wide fit gives a no-roll, secure feel that stays in place as you move. While not meant for overnight or heavy flow, this period swimwear is a great choice for short swims, light days, or as backup protection with a tampon or cup — so you can enjoy water activities with comfort and confidence.

Swimwear That Holds 40ml. Seriously.

Our period swimwear features fast-absorbing layers that lock in moisture in seconds, helping reduce leaks when you're in or around water. The absorbent zone holds up to 40ml (about 4 tampons), giving you powerful protection for light to moderate flow. Built-in side leak barriers add extra defense against side leaks. While not made for all-day or overnight use, this swimwear is ideal for short swims, pool days, and light period backup — so you can move freely and feel secure.

No Chemical PFAS Period Swimsuit

NO TOXIC CHEMICAL PFASPFAS aren’t just one chemical — they’re a large group of over 12,000 substances that break down very slowly, meaning they can stay in your body and the environment for a long time. Some menstrual products, including period underwear, may contain PFAS to boost absorbency or resist stains. Unfortunately, many brands may not realize PFAS are present because they can be hidden in the raw materials they use. We take a different approach: our period products are made with PFAS-free materials that are safe, breathable, and comfortable. They still deliver strong leak protection and all-day freshness. Every piece is carefully tested to ensure it meets high standards for safety and your well-being — period care that puts your health first.

High-Stretch, Long-Lasting Swimwear

This swimwear is made from fade-resistant, chlorine-safe fabric, ideal for repeated pool use without losing color or shape. The four-way stretch design allows full freedom of movement and ensures a snug, comfortable fit. Quick-dry technology helps water drain quickly, avoiding that cold or sticky feeling after swimming. The suit stays securely in place, offering reliable support during all kinds of water activities — with no slipping or constant readjusting.

UPF 50+ (Customizable)

This period swimwear features UPF 50+ sun protection, blocking over 98% of harmful UV rays. It's an ideal choice for outdoor swimming, beach activities, or any extended sun exposure. The built-in UV defense helps protect your skin without needing extra sunscreen under the fabric, making it safer and more convenient for everyday wear.

Still have Questions?

We have answers.

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.

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.

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!

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.

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!)
