Menstrual underwear 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 panties. Although insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining serves as a soft, built-in panty liner inside the menstrual 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 unbleached natural): for sensitive skin or prone to infections which allows you to see menstrual flow. Black: For easier care since persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier stitched into the underwear is made of a thin layer of 100% PUL. This makes the menstrual underwear impermeable to any blood leaks that might try to pass through it.
Light or heavy flow for period underwear?
The menstrual underwear adapts well to all flow levels. For added comfort, women with a heavy flow may prefer wearing a Diva Cup cup or of a menstrual disc. For light to medium flow, the menstrual brief with 3 inserts is sufficient for daytime. The insert also allows you to change only the inner layer 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:
-
Un insert by day or by night Marie thread (optional) :
- Provides a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Snaps onultra-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 skin, whether on your period or not. And together, more than ever, we’re helping make an important eco-responsible choice 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 reduce odors
• Hypoallergenic to eliminate irritation
• Maximum absorption
• Soft when mixed with cotton
