Menstrual panties made in Quebec
Discreet lining in natural fibers
An absorbent lining is already present in the period underwear to create a natural barrier for the panties. While not sufficient without a menstrual insert, it helps prevent unexpected leaks. The lining serves as a soft, built-in panty liner inside the period underwear. It is longer at the front and back than standard sewing patterns to ensure perfect protection.
The lining is offered in two colors. Natural (color natural unbleached): for sensitive skin or skin prone to infections that allows you to see menstrual flow. Black: For greater ease of maintenance since persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier sewn into the underwear is made of a thin 100% PUL layer. This makes the menstrual underwear invincible to any blood leaks trying to pass through.
Flux: light or heavy for a period panty?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow might prefer wearing a Diva Cup cup or of a menstrual disc. For light to medium flow, the menstrual panties with 3 inserts are sufficient for daytime. The insert also allows you to change only the interior without having to change the underwear during the day.
Insert removable menstrual
It is possible to add a removable insert to the panties to easily adapt to the menstrual cycle:
-
One insert for day or night Marie thread (optional) :
- 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.
Wearing the Marie fil period panties means choosing to be comfortable and confident in your skin, whether you have your period or not. And together, more than ever, we’re helping make an important eco-responsible gesture for the environment. 💚

Why choose hemp?*
Hemp is the future for the environment. Its processing requires
very little water and no chemicals. That's why Marie prefers hemp to bamboo. This fabric also has several properties:
• Antibacterial to reduce odors
• Hypoallergenic to eliminate irritation
• Maximum absorbency
• Soft when blended with cotton

Marie menstrual underwear size chart
Order the right size of menstrual underwear by measuring your hips, above the buttocks, using a tape measure held parallel to the floor. If you are between two sizes, choose the larger one. Periods often come with a bloated or sore belly.
