Frequently asked questions

Your questions, answered

Absorbency, size, materials, washing: everything you need to know before choosing your period panties.

Which organic cotton menstrual panties should I choose?

Ara absorbs the equivalent of 2 tampons and Aquilla the equivalent of 4 tampons, both for up to 8 hours, in sizes XS/34 to XXL/44. For teens: Libra (2 tampons) and Lyra (4 tampons, up to 8 hours).

What certifications does the organic cotton range have?

The cotton in Ara and Aquilla is GOTS certified (Global Organic Textile Standard), and both models are certified PFAS-free.

Organic cotton or microfibre: which should I choose?

For the same absorption, the difference lies in the fabric and the wear time: organic cotton (Ara, Aquilla) is a natural, soft and breathable fabric, for up to 8 hours; microfibre (Séléné, Artémis), with its second-skin feel, lasts up to 12 hours.

Discover all the benefits of this product, how it works, and how to choose the model that best suits your needs. You can also explore our full collection of period underwear.

What is organic cotton period underwear?

Organic cotton period underwear is reusable underwear with an integrated absorbent zone capable of retaining menstrual blood while offering optimal comfort.

Organic cotton plays a key role in period panties: it is grown without pesticides. It is a breathable, soft fabric, pleasant every day and very pleasant to wear.

The structure of the underwear generally includes:

  • a layer of organic cotton, the one directly in contact with the skin,

  • a second absorbent layer capable of holding menstrual flow,

  • a waterproof yet breathable barrier to prevent leaks,

  • a comfortable outer fabric suited for daily wear.

Organic cotton enhances comfort while ensuring better skin tolerance, making it an ideal option for those wishing to avoid synthetic materials.

Why choose organic cotton period underwear?


Choosing organic cotton period underwear means combining performance and comfort while adopting a more sustainable approach. This type of product offers several benefits:

  • Natural comfort and softness: organic cotton is soft and breathable. It feels natural, even during heavier-flow days.
  • Effective absorption: organic cotton period underwear is designed to absorb menstrual flow without feeling damp. It is suitable for light, medium, or heavy periods depending on the model. Some cuts can be worn both day and night.
  • A durable and economical alternative: washable period underwear reduces waste from disposable products. They can be reused for several years, making them a long-term, cost-effective investment.
  • Breathable materials: organic cotton allows better airflow compared to synthetic fibers. It helps limit unwanted odors, supports intimate balance, and enhances freshness throughout the cycle.
