Menstrual underwear made in Quebec
Discreet lining in natural fibers
An absorbent lining is already present in the menstrual brief to create a natural barrier to the underwear. Although insufficient without a menstrual insert, it helps prevent surprises. The lining acts as a soft panty liner integrated into the menstrual brief. 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 skin prone to infections that allows you to see menstrual flow. 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 invincible against any blood leaks trying to pass through it.
Light or heavy flow for menstrual underwear?
The menstrual underwear adapts well to all flows. For greater comfort, women with a heavy flow may prefer wearing a Diva Cup cup or of menstrual cupFor light to medium flow, the menstrual briefs with 3 inserts are sufficient for daytime. The insert also lets you 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 night Marie thread (optional) :
- Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Snaps on (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.

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
