Materials

At Lunã, we believe comfort starts with what you wear against your skin. That’s why we carefully choose our materials, with a focus on quality, skin-friendliness and everyday comfort. We use fabrics that feel good, are suitable for daily skin contact and do exactly what they’re meant to do. The result is underwear that feels soft, reliable and comfortable — just as you deserve.

Any questions?

Is it hygienic?

Yes, our period swimwear is hygienic. It features a special antibacterial layer that helps eliminate bacteria and neutralise odours, keeping the underwear clean and fresh throughout wear.

How long can I wear the bikini?

Our bikini can be worn for up to 12 hours, depending on the intensity of your flow. For heavier flows, we recommend choosing our 3-drop protection.

Won't it smell?

No, not at all! Thanks to the special antibacterial layer, any unwanted odours are eliminated, keeping our bikini fresh throughout the day.

Doesn't it feel wet?

No, thanks to our special 4-layer technology, all moisture is absorbed, so it doesn’t feel wet against your skin.

Doesn't the bikini feel bulky?

No, most women don’t notice the thickness while wearing it. Only the absorbent area has extra layers, making that part slightly thicker — but not in an uncomfortable or visible way. The rest of the bikini is just as thin as regular underwear. This means you feel protected against leaks without discomfort, and it remains breathable, unlike pads.

How do I choose the right size?

To choose the right size, you can use the size chart above. In general, you can stick to your usual size. Most women find that our bikini fits true to size. If a specific style runs smaller, this is clearly indicated on the product page.
