Menstrual panties made in Quebec
Discrete lining in natural fibers
A lining is already present in the menstrual underwear to create a natural barrier for the underwear. Although insufficient without a menstrual insert, it helps prevent unexpected 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 (unbleached natural shade): for sensitive or infection-prone skin, allowing the menstrual flow to be visible. Black: For easier maintenance since stubborn stains are not visible.
Breathable, waterproof barrier inside the period underwear
A breathable, waterproof barrier sewn inside the panties is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks that might try to pass through it.
Light or heavy flow for a menstrual brief?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow may prefer wearing a Diva Cup cup or of menstrual disc. For light to medium flow, the menstrual panties alone are sufficient for daytime use. An insert also allows you to change only the inner pad without having to change the panties during the day.
Replaceable menstrual insert
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 with snap fasteners (hyper-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 menstrual underwear means choosing to be comfortable and feel good in your skin, whether you’re menstruating or not. And together, more than ever, we’re helping to 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. It's for that reason Marie prefers hemp to bamboo. This fabric also has several properties:
• Antibacterial to reduce odors
• Hypoallergenic to eliminate irritation
• Maximum absorption
• Soft when blended with cotton

Size chart for Marie fil menstrual briefs
Order the correct size of period panties 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. Menstrual periods often come with a bloated or sore stomach.
