Menstrual panties made in Quebec
Discreet lining in natural fibers
An absorbent 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 patterns to ensure perfect protection.
The lining is offered in two colors. Natural (color natural unbleached): for sensitive skin or prone to infections which allows the menstrual flow to be seen. 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 consists of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks that might try to pass through.
Light or heavy flow for menstrual panties?
The menstrual underwear adapts well to all flows. For more comfort, women with a heavy flow may prefer wearing a Diva Cup cup or of a menstrual disc. For a light to medium flow, the menstrual brief with 3 inserts is sufficient for daytime use. The insert also allows you to change only the interior 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) :
- Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens with snap fasteners (ultra-thin, you won't feel them, we 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 briefs means choosing to be comfortable and feel good in your skin, whether you have your period or not. And together, more than ever, we're helping make an important eco-friendly 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 absorption
• Soft when blended with cotton
Choose the right size for 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 size chart.
Marie menstrual underwear size chart
Order the right size of period underwear by measuring your hips, above the buttocks, using a tape measure held parallel to the floor. If you're between sizes, choose the larger one. Periods often come with a bloated or sore stomach.
