High-Waist Menstrual Brief + Keepsake Lilac
La high-waist menstrual panties + Marie fil, it's the comfort of regular underwear but designed for all the little everyday leaks up to menstruation.
High-waist menstrual underwear + was designed with real life in mind
The high-waist + menstrual panties are well enveloping, slim the silhouette and made entirely from natural fibers. This one covers your stomach up to the navel.
Its absorbent, waterproof lining serves a dual purpose. It acts as a built-in soft protective layer permanently attached inside the underwear.
The lining of the period panties acts as an ultra-soft built-in liner inside. But because we like the panties to adapt easily to the menstrual cycle, it is possible to add a insert by day or by 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-waisted menstrual underwear + with insert
The inserts that fit into the Marie fil menstrual underwear let you adapt the underwear to your flow.
- Assures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens with snap buttons (super thin, you won't feel them, promise!), to stay securely in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.
Pour un flux léger ou en duo avec votre coupe menstruelle, la culotte menstruelle seule est suffisante pour la journée.
The high-waist + menstrual underwear with natural or black absorbent
Each woman is different. That's why we offer the pad in two color options:
- Naturelle: unbleached and undyed, for sensitive or infection-prone skin. Also a good choice if you like to visually track your menstrual flow.
- Noire: for easier maintenance.
Wearing the Marie Fil menstrual 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 of washable period 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 correct size of period 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 aching belly. The goal is to get comfortable period underwear!

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