Menstrual underwear made in Quebec
Discrete lining in natural fibers
An absorbent lining is already present in the period underwear to create a natural barrier for the panties. While insufficient on its own without a menstrual insert, it helps prevent unexpected leaks. The lining acts 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 available in two colors. Natural (color natural unbleached): for sensitive skin or skin prone to infections 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 into the inner layer of the underwear consists of a thin 100% PUL layer. This makes the menstrual underwear impervious to any blood leaks that might try to pass through.
Light or heavy flow for menstrual underwear?
The menstrual briefs adapt well to all flows. For greater comfort, women with a heavy flow may prefer to wear a Diva Cup cutter ou d'un menstrual disc. For a light to medium flow, the menstrual panties with 3 inserts are sufficient for daytime use. The insert also allows you to change only the inner pad 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 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 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 feel good in your skin, whether 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. That's why 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
