Menstrual briefs made in Quebec
Discreet lining in natural fibers
A moisture-wicking lining is already present in the menstrual underwear to create a natural barrier for the panties. Although insufficient without a menstrual insert, it helps prevent leaks. The lining acts as a soft, built-in panty liner inside the menstrual underwear. It is longer at the front and back than standard sewing templates to ensure perfect protection.
The lining is offered in two colors. Natural (color natural unbleached): for sensitive skin or prone to infections that allows you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable, waterproof barrier inside the menstrual panty
A breathable, waterproof barrier sewn into the inside of the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks trying to pass through.
Light or heavy flow for menstrual underwear?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow might prefer wearing a Diva Cup menstrual cup ou d'un menstrual disc. For light to medium flow, the period underwear with 3 inserts is sufficient for daytime use. The insert also allows you to change only the interior 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:
-
Un insert by day or by night Marie thread (optional) :
- Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Snaps onultra-thin, you won't feel them, promise!), to stay firmly in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.
Wearing the Marie fil menstrual underwear means choosing to be comfortable and at ease in your skin, whether menstruating 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. Processing it requires
very little water and no chemicals. That's why Marie prefers hemp to bamboo. This fabric also has several properties:
• Antibacterial to limit odors
• Hypoallergenic to eliminate irritation
• Maximum absorption
• Soft when blended with cotton

Size chart for Marie fil menstrual underwear
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’re between two sizes, choose the larger one. Periods often come with a bloated or sore stomach.
