Menstrual panties made in Quebec
Discreet lining in natural fibers
A moisture-wicking liner is already present in the menstrual underwear to create a natural barrier for the panty. Although insufficient without a menstrual insert, it helps prevent surprises. The liner 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 unbleached natural): for sensitive skin or prone to infections which allows the menstrual flow to be visible. Black: For easier maintenance since persistent stains are not visible.
Breathable, 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 impervious to any blood leaks that might try to pass through it.
Light or heavy flow for a menstrual brief?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow may prefer to wear a Diva Cup cup ou d menstrual cup. For light to medium flow, the menstrual panties with 3 inserts are sufficient for daytime. The insert also lets you change just the liner 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:
-
One insert by day or by night Marie thread (optional) :
- Assure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Attaches using snap fasteners (hyper 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 briefs means choosing to be comfortable and feel good in your own skin, whether you're menstruating or not. And together, more than ever, we're helping make a meaningful eco-responsible gesture for the environment. 💚

Marie menstrual underwear size chart
Order the right size of period 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 a bloated or sore belly.
