Plus High Flora and Fauna Menstrual Panties
The Marie menstrual brief looks like a regular women's underwear, except it is perfectly adapted for periods. Indeed, this feminine menstrual protection allows women to lead an active life every week of the month... And all this while being an eco-responsible alternative!
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. Although insufficient without a menstrual insert, it helps prevent mishaps. 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 offered in two colors. Natural (color natural unbleached): for sensitive skin or prone to infections which 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 underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear invincible to any blood leaks that would try to pass through it.
Light or heavy flow for menstrual panties?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow might prefer wearing a Diva Cup cup or of a menstrual disc. For light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime. The insert also allows you to 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) :
- Ensures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Sets 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 brief means choosing to be comfortable and feel good in your skin, whether you have your period or not. And together, now more than ever, we’re helping make an important 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 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.
Size chart for Marie Fil menstrual panties
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 two sizes, choose the larger one. Periods often come with a bloated or sore stomach.
