Boreal Leaves Menstrual Briefs
The Marie period panties look like a regular pair of women's briefs, except they are perfectly adapted for menstruation. Indeed, this feminine menstrual protection allows women to lead an active life every week of the month... And all while being an eco-friendly alternative!
Menstrual underwear made in Quebec
Discrete 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 acts as a soft, integrated 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 available 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, waterproof barrier inside the menstrual underwear
Une breathable, waterproof barrier sewn into the inside of the panty is made of a thin layer of 100% PUL. This makes the menstrual panty invincible to any blood leaks that might try to pass through it.
Light or heavy flow for menstrual panties?
The menstrual underwear adapts well to all flows. For more comfort, women with a heavy flow may prefer wearing a Diva Cup cup ou d'un menstrual disc. For light to medium flow, the menstrual briefs with 3 inserts are sufficient for daytime. The insert also allows you to 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 by night Marie thread (optional) :
- Ensures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Attaches with snap fasteners (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.

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
