Lunette Period Panties: period underwear in sizes XXS to 5XL
Lunette Period Panties are period underwear that looks and feels like everyday underwear, with an absorbent gusset that holds up to one menstrual cup or three tampons of blood. Wear them on their own on light to medium days, or with your Lunette menstrual cup. They come in ten sizes, from XXS to 5XL.
What are Lunette Period Panties?
Period panties, also called period underwear or period pants, are underwear with an absorbent gusset built in, so there is nothing to insert and nothing to throw away. You wear them, wash them and wear them again.
Lunette Period Panties are made ethically in the EU from Oeko-Tex certified fabrics. The high gusset and wide waist panel give full coverage.
How much do they hold?
The gusset holds up to one menstrual cup or three tampons of blood. In practice:
- Light to medium flow: wear them on their own.
- Heavier days: wear them with your Lunette cup.
- While you learn to use a cup: wear them with your Lunette menstrual cup in the first cycles. A menstrual cup that sits right doesn't leak, and the panties cover you while you learn the fold and the seal.
How the layers work
- Next to your skin: a breathable gusset in 100% organic cotton.
- Inside: absorbent inner layers that hold the moisture (90% polyester, 10% polyamide).
- Outside: a laminated layer that stops it leaking through (100% laminated polyester).
- Main fabric: 95% lyocell, 5% elastane.
Sizes: XXS to 5XL
Lunette Period Panties come in XXS, XS, S, M, L, XL, XXL, 3XL, 4XL and 5XL. Choose by hip measurement: measure the widest point, just above your seat, snug and in centimetres.

|---|---|
| XXS | 84–87 |

They fit snug to protect against leaks, so if you are unsure, choose one size bigger than usual. You pick your size on the Lunette Period Panties product page.
Washing and care
- Machine wash at 40 °C; an occasional 60 °C wash is fine.
- Hang them to dry.
- Skip the tumble dryer: heat can affect the laminated layer that stops leaks.
Period panties and a menstrual cup
The two work well together. On light days, the panties are enough on their own. On heavier days, the Lunette menstrual cup collects your flow and the panties are there as back-up. For how period underwear works in more detail, read our period underwear guide.
