4 Layers Swim 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. 50+ UPF
You can choose organic cotton or bamboo fiber for the main fabric. Both are soft, breathable, and good for the skin.

Leakproof Swimwear with 40ml Absorbency
Engineered for discreet performance, this swim period underwear features a built-in absorbent core capable of holding up to 40ml of menstrual fluid. The design remains smooth and streamlined in water, without visible swelling or bulk. It offers reliable protection for short swims or water activities, especially during light to moderate flow. With secure fit, leak-resistant construction, and water-adaptive materials, it’s a functional solution for customers seeking comfort, movement, and protection — all in one garment.
No Toxic PFAS Period Swimwear
This swim period underwear is made without PFAS, a class of synthetic chemicals known for their long-term persistence in the environment and the human body. Commonly referred to as “forever chemicals,” PFAS have been used in some textile treatments to enhance liquid resistance, including in menstrual products. However, their potential health and environmental impacts have raised increasing concerns. This swimwear uses only PFAS-free materials and does not rely on chemical coatings for absorbency or leak protection. Instead, its multi-layer structure manages menstrual flow through physical absorption and barrier design, ensuring both functionality and material safety. All components are tested to meet relevant safety and performance standards.
Four-way Stretch & Elegant Outfit
This swimwear is made to offer both comfort and a clean, elegant look during your period. The fabric stretches in all directions, so it fits well and moves with the body when swimming or walking. Even after getting wet, it stays smooth and does not change shape or become bulky. Inside, the hidden absorbent layers help manage period flow without being seen or felt. The material is soft, dries quickly, and stays dark when wet. It also includes features that reduce odor and help keep the skin fresh. This design is a simple and smart choice for people who want period protection without giving up style or freedom of movement.
