Menstrual Panties High Waist +
La high-waist menstrual underwear + Marie thread, it's the comfort of regular underwear but designed for all the little everyday leaks up to menstrual flow.
High-waist menstrual underwear + was designed for real life
La culotte menstruelle taille haute + is well enveloping, slims the silhouette and made entirely from natural fibersThis one covers your stomach up to the navel.
Its absorbent, waterproof lining serves a dual purpose. It acts as a soft, permanently integrated underlayer protector inside the underwear.
The lining of the period underwear acts as an ultra-soft built-in panty liner. But because we like the underwear to easily adapt to the menstrual cycle, it is possible to add a insert for day or night Marie thread (optional).
Each menstrual panty has a breathable, waterproof barrier :
- composed of a thin 100% PUL layer, making your menstrual underwear invincible to any leak that would try to pass through it.
High-waist menstrual underwear + with insert
The inserts that fit into the Marie fil menstrual underwear allow you to adapt the underwear to your flow.
- Ensure a double absorbent, waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Attaches using snap fasteners (ultra-thin, you won't feel them, we promise!), to stay securely in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.
For a light flow or paired with your menstrual cup, the menstrual underwear alone is sufficient for daytime.
High-waist + menstrual panties with natural or black absorbent
Every woman is different. That's why we offer the pad in two color options:
- Naturelle: unbleached and undyed, for sensitive skin or skin prone to infections. Also a good choice if you like to visually monitor your menstrual flow.
- Noire: for easier maintenance.
Wearing the Marie fil period underwear means choosing to be comfortable and at ease in our skin, whether menstruating or not. And together, more than ever, we are making an important eco-responsible gesture for the environment. 💚

Choose the right size for washable menstrual underwear:
Buying menstrual underwear online isn't easy. You never know if the fit will be right for you. I understand you.
To order the right size of menstrual underwear, measure your hips above the buttocks using a tape measure held parallel to the floor. If you're between two sizes, choose the larger one. Periods often come with a bloated or sore belly. The goal is to have comfortable period underwear!

If the menstrual underwear still doesn't fit despite this precaution, it can be exchanged according to the return and exchange policy and in compliance with all of the following conditions:
- The menstrual briefs must not have been worn with another undergarment underneath for trying on.
- It must not have been washed or used.
- It must be returned in the same condition in which it was sent to you.
