Culotte menstruelle made in Quebec
Discreet lining in natural fibers
Une absorbent lining is already present in the period underwear to create a natural barrier for the panties. Although insufficient without a menstrual insert, it helps prevent mishaps. The lining acts as a soft, integrated panty liner inside the period 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 skin prone to irritation that allows you to see menstrual flow. Black: For easier maintenance since persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier sewn inside the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear impervious to any blood leaks that might try to pass through it.
Light or heavy flow for period underwear?
The period underwear adapts well to all flows. For more comfort, women with a heavy flow might prefer wearing a Diva Cup cup or of menstrual cup. For light to medium flow, the menstrual briefs with 3 inserts are sufficient for daytime use. The insert also allows you to change only the inner layer without having to change the underwear during the day.
Insert removable menstrual
It is possible to add a removable insert to the underwear to easily adapt to the menstrual cycle:
-
One insert by day or by night Marie thread (optional) :
- Ensures 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 even 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 menstrual underwear means choosing to be comfortable and feel good in your skin, whether you have your period or not. And together, more than ever, we help 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 irritations
• Maximum absorption
• 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 stomach.
