Leaves High Waist Menstrual Panties

Menstrual panties made in Quebec
Discreet lining in natural fibers
An absorbent lining is already present in the menstrual panties to create a natural barrier for the underwear. While insufficient without a menstrual insert, it helps prevent unexpected leaks. The lining acts as a soft, built-in panty liner inside the menstrual 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 (color natural unbleached): for sensitive skin or prone to infections which allows you to see menstrual flow. Black: For easier maintenance as persistent stains are not visible.
Breathable and waterproof barrier inside the menstrual underwear
A breathable, waterproof barrier sewn inside 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.
Light or heavy flow for menstrual panties?
The period underwear adapts well to all flows. For greater comfort, women with a heavy flow might prefer wearing a Diva Cup cup ou d menstrual disc. For a light to medium flow, the menstrual underwear with 3 inserts is sufficient for daytime use. 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:
-
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.
- Se fixe à l’aide de boutons-pression (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 underwear means choosing to be comfortable and at ease in your own skin, whether you have your period or not. And together, now more than ever, we’re helping make 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 reduce odors
• Hypoallergenic to eliminate irritations
• Maximum absorption
• Soft when blended with cotton

Marie menstrual underwear size chart
Order the right size of menstrual 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 belly.
