Period underwear: designed for ultimate comfort and peace of mind
Our Period underwear is designed to support you through every stage of your period — from light to medium flow, day and night. The Underwear fits perfectly, feels like regular underwear, and provides protection without unnecessary bulk. Thanks to the breathable and absorbent layers, moisture is safely captured and you stay fresh. This means you can continue with your daily routine — working, exercising, sleeping, or traveling — without worrying about leaks.
Whether you choose classic Underwear, a hipster, a thong, or boyshorts: every style offers the same reliable protection and softness.
How does Period underwear work?
Period underwear for women contains smart multi-layer technology that absorbs menstrual flow, neutralizes odors, and prevents leaks.
It consists of:
• A soft, comfortable absorbent layer against the skin.
• A protective, water-repellent layer that prevents leaks.
• A flexible outer layer that stays dry, fresh, and discreet throughout the day.
You wear it like regular underwear. Depending on your flow, you can wear Period underwear for two to four hours before changing — and even longer with light flow. Would you like to learn more about how the technology works? Check out our blogs or our FAQ.
Why do women choose Period underwear?
More and more women are choosing Period underwear because it is:

• Durable and usable for several years
• Discreet under all types of clothing
• Reliable at work, during exercise, and overnight

Care: how can you make your Period underwear last longer?
Proper care ensures a long lifespan. Always rinse your Underwear in cold water after use. Then machine wash at 30–40°C without fabric softener. You can wash it with your dark laundry! Leave it to air-dry. To prevent your Underwear from being damaged by other garments, we recommend placing it in a laundry bag.
