How does it work?
Absorbent underwear may take a little getting used to. We understand that you might have questions: how does it work exactly, is it really hygienic, and does it offer enough protection? That’s why we answer all your questions here — so you know exactly what to expect.
Lunã’s four-layer absorbent underwear is designed to provide effective protection against moisture leaks. Each layer has a specific function that helps absorb and retain moisture, so you can feel fresh and dry throughout the day.
Together, these four layers ensure that moisture is quickly absorbed, evenly distributed, and safely locked away. This helps prevent leaks and allows you to feel comfortable and confident. The underwear is reusable, easy to wash, and made to be worn again and again.
Our absorbent underwear is designed with a smart, layered construction. Each layer does its job, so you can feel fresh, dry, and comfortable all day long — whether you’re dealing with blood, bladder leaks, or simply want a bit of extra reassurance.
1. Comfort layer
This soft, breathable inner layer feels just like regular underwear. It sits directly against your skin and is so comfortable that you’ll almost forget you’re wearing extra protection.
2. Absorbent layer
This layer quickly absorbs moisture and spreads it evenly, so it feels fresh and doesn’t build up in one spot. Ideal if you want extra security without a wet feeling.
3. Moisture barrier
This layer prevents leaks completely. At the same time, it helps neutralise odours, so you can go about your day with confidence.
4. Antibacterial outer layer
The outer layer keeps everything securely contained and helps protect your skin from irritation. Waterproof and antibacterial, without feeling heavy or stiff.
Our underwear contains a specially absorbent layer that has been treated with an antibacterial finish. This ensures hygienic performance and actively helps prevent unwanted odours. The treatment is skin-safe, free from harmful substances, and suitable for everyday use.
So you can wear it with confidence, without worrying about irritation or what comes into contact with your skin. The carefully selected materials keep you feeling fresh, dry, and comfortable — all day long.
Yes — and even more so: our absorbent underwear is designed to keep you feeling fresher and better protected for longer than many disposable products such as tampons, pads, or panty liners. And that starts with smart materials and a carefully designed layered structure.
Lunã’s underwear is made from breathable, moisture-regulating fabrics that ensure moisture is quickly absorbed and evenly distributed. Unlike disposable products, which often stay damp and clammy, our underwear keeps the inside drier — helping to limit bacterial growth.
In addition, the absorbent layer features an antibacterial finish. This has been specially developed to reduce unwanted bacteria and neutralise odours, without harmful substances or irritating additives. Everything is skin-safe, dermatologically responsible, and designed for long-term use.
Because the underwear draws moisture inward and locks it away, you don’t have direct contact with the moisture itself — making it cleaner than you might expect. You don’t need to change it every hour, as with tampons or pads. As long as you follow our wear guidelines, you can wear the underwear safely and hygienically throughout the day.
No, that’s not necessary. Our absorbent underwear is designed to be worn on its own, without pads, tampons, panty liners, or incontinence products.
Thanks to its smart, multi-layer construction, it can absorb significantly more moisture than many disposable products. This means you get reliable protection and long-lasting comfort without needing anything extra.
If you feel more comfortable combining it with another product at first, that’s absolutely fine. But it’s not required — Lunã is made to handle it all on its own.
No! Our underwear is designed with multiple absorbent layers that help prevent leaks. The special construction and materials ensure that moisture is effectively absorbed and securely locked away. This provides reliable protection for menstruation, sweat, or bladder leaks.
As long as you stay within the indicated absorption level, there’s no need to worry about leakage. If the underwear does reach its capacity, you’ll naturally notice it — the top layer against your skin will start to feel damp. That’s a clear signal that it’s time to change. This way, you stay fresh, dry, and protected all day long.
No. Our underwear is designed to absorb moisture quickly and keep you feeling dry and comfortable. The inner layer — which sits directly against your skin — is quick-drying and moisture-permeable. As soon as moisture comes into contact with it, it is immediately drawn down into the absorbent core underneath, where it is safely locked away.
Because the top layer stays dry, the underwear doesn’t feel wet while wearing it. This prevents a clammy feeling and ensures you hardly notice it at all. You can rely on long-lasting freshness and comfort, all day long.
Choosing the right Lunã absorbent underwear depends on the amount of moisture you usually experience — whether that’s from menstruation, bladder leaks, sweat, or other forms of moisture. We offer three different flow levels, so you can always choose the protection that suits you best.
1. Flow level 1 (1 drop)
Suitable for light days or light bladder leaks. This flow level absorbs roughly the same as 1 to 2 tampons, panty liners, or pads. Ideal if you’re looking for subtle, comfortable protection.
2. Flow level 2 (2 drops)
Perfect for moderate menstrual flow or daily bladder leaks. This is comparable to around 2 to 4 tampons or pads. A great option if you want a bit more reassurance without compromising on comfort.
3. Flow level 3 (3 drops)
This option is available in two models:
– The period model absorbs up to 6 to 8 tampons’ worth of blood.
– The incontinence model is specially developed for bladder leaks and absorbs up to 200 ml of liquid.
Both models offer maximum protection and are designed for comfort without sacrificing reliability.
It’s important to be aware of your own pattern of menstrual flow or moisture loss when making your choice. If you’re unsure, start with the flow level that most closely matches what you normally use in tampons, pads, or incontinence products. You can then easily adjust based on your own experience.
Whatever you choose, Lunã is designed to be comfortable, safe, and worry-free — day after day.
To wash it, first rinse the underwear thoroughly with cold water after use to remove most of the blood or moisture. You can then wash it in the washing machine at 30°C using a mild detergent.
You might wonder: is 30°C hygienic enough? Yes — our underwear is specifically designed to be hygienically clean at lower temperatures. The absorbent layer has an antibacterial treatment that helps prevent bacterial growth, even at 30°C. Combined with a good detergent and rinsing beforehand, the underwear is thoroughly cleaned without the need for higher temperatures. In fact, washing at higher temperatures can reduce the effectiveness of the absorbent layers.
We recommend washing your Lunã underwear in the Lunã wash bag. This helps protect the material during washing and extends its lifespan.
After washing, let the underwear air dry and do not use fabric softener, as this can reduce absorbency.
