Menstrual panties 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 without a menstrual insert, it helps prevent surprises. The lining serves 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 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 inside the panties is made of a thin 100% PUL layer. This makes the period panties impervious to any blood leaks that might try to pass through.
Light or heavy flow for menstrual underwear?
The menstrual underwear adapts well to all flow levels. For greater comfort, women with a heavy flow may prefer to wear a Diva Cup cutter or of a menstrual cup. For a light to medium flow, the menstrual panties with 3 inserts are sufficient for daytime use. The insert also lets you 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 panties to easily adapt to the menstrual cycle:
-
One 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 on (ultra-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 own skin, whether you have your period or not. And together, more than ever, we’re helping to make a meaningful eco-responsible contribution to 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 absorbency
• Soft when mixed with cotton
