Menstrual panties made in Quebec
Discrete lining in natural fibers
An absorbent lining is already present in the menstrual panties to create a natural barrier for the underwear. While insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft, built-in panty liner inside the menstrual panties. 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 unbleached natural): for sensitive skin or skin prone to infections which allows you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable, waterproof barrier inside the menstrual underwear
Une breathable, waterproof barrier sewn into the inside of the brief is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks that would try to pass through it.
Light or heavy flow for menstrual underwear?
The menstrual underwear adapts well to all flows. For greater comfort, women with a heavy flow might prefer wearing a Diva Cup cutter ou d'un menstrual disc. For light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime. The insert also lets you change only the inside without having to change the underwear during the day.
Removable menstrual insert
It is possible to add a removable insert to the underwear to easily adapt to the menstrual cycle:
-
A insert of day or night Marie thread (optional) :
- Assure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens with 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.
Porting the Marie Fil period panties means choosing to be comfortable and feel good in your skin, whether you have your period or not. And together, more than ever, we’re helping make a meaningful 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 irritations
• Maximum absorption
• Soft when blended with cotton

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