High-waist Menstrual Panties Monstera and Roses
The Marie Fil period panty looks like a regular women's underwear, except it's perfectly designed for your period. This menstrual protection lets women stay active every week of the month... While being an eco-responsible alternative!
Menstrual panties made in Quebec
Discreet lining in natural fibers
A lining is already present in the period underwear to create a natural barrier for the garment. Although insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft, built-in underwear protector inside the period panties. It is longer at the front and back than standard sewing templates to ensure perfect protection.
The lining is available in two colors. Natural (unbleached natural shade): for sensitive or infection-prone skin, allowing 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 underwear 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 panty?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow may prefer wearing a Diva Cup cutter or of menstrual cup. For a light to medium flow, the menstrual brief alone is sufficient for daytime. An insert also allows you to change only the inner layer without having to change the entire brief during the day.
Removable menstrual insert
It is possible to add a removable insert to the panties to easily adapt to the menstrual cycle:
-
A insert day or 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 panties means choosing comfort and feeling good in your skin, whether you have your period or not. And together, more than ever, we’re making 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 limit odors
• Hypoallergenic to eliminate irritation
• Maximum absorbency
• Soft when blended with cotton
Choose the right size of washable menstrual underwear:
Buying menstrual underwear online can be tricky. Every woman deserves a proper fit and to be comfortable during her period. Here are some tips regarding the Marie fil sizing chart.
Size chart for Marie fil menstrual briefs
Order the right size of menstrual underwear by measuring your hips, above the buttocks, using a measuring tape held parallel to the floor. If you’re between two sizes, choose the larger one. Periods often come with bloating or a sore belly.
