High-Waist Menstrual Briefs + Red
The high-waist menstrual underwear + Marie thread, it's the comfort of a regular underwear but designed for all the little everyday leaks up to menstrual flow.
The high-waist + menstrual underwear was designed with real life in mind
La culotte menstruelle taille haute + is nicely enveloping, smooths the figure and made entirely from natural fibres. This one covers your stomach up to the navel.
Its absorbent, waterproof lining serves a dual purpose. It acts as a soft protective layer permanently built into the underwear.
The lining of the period panties acts as a built-in, super-soft panty liner inside. But because we like the underwear to easily adapt to the menstrual cycle, it is possible to add a insert 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-waisted menstrual panties + with insert
Les inserts qui s'installent dans la culotte menstruelle Marie fil permettent d'adapter la culotte à votre flux.
- Ensure a double absorbent and 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, 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.
The high-waist + menstrual underwear with natural or black absorbent
Every woman is different. That's why we offer the pad in two color options:
- Natural: unbleached and undyed, for sensitive or infection-prone skin. 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 comfort and feeling good in our skin, whether we have our period or not. And together, now more than ever, we’re making an important eco-responsible gesture for the environment. 💚
The washable Marie menstrual brief in detail
- 1 high-waist menstrual brief (as shown in the main photo), lovingly made in Quebec, for real (hello to my seamstresses Marie-Ève and Laura💚)
- Optional: day and/or night insert(s)
The panties:
Composition:
95% organic cotton
+
5% elastane

100% comfortable
The lining: what touches your most sensitive area
Absorption level: 340 GSM (grams/square meter)
(That's my little geeky side wanting to point it out just because it's the kind of thing I find fun to know. Concretely, it's equivalent to an undergarment protector, luxury version)
Composition:
45% hemp*
+
55% organic cotton
=
100% natural
* Hemp is truly the future for the environment. Its processing requires
very little water and no chemicals. It's simple, he has it all going for him:
• antibacterial (goodbye bad odors)
• hypoallergenic (no more irritation or itching)
• top of the class in terms of absorption
• blended with cotton, it's a really gentle match for the skin
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.
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 sizes, choose the larger size. Periods often come with bloating or soreness. The goal is to get comfortable period underwear!

If the menstrual brief 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:
- La culotte menstruelle 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.
