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 mishaps. 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 patterns to ensure perfect protection.
The lining is offered 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 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 impervious to any blood leaks that might try to pass through it.
Light or heavy flow for a period underwear?
The period underwear adapts well to all flow levels. For added comfort, women with a heavy flow may prefer wearing a Diva Cup menstrual cup or of menstrual disc. For light to medium flow, the period underwear 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 panties to easily adapt to the menstrual cycle:
-
One insert for day or night Marie thread (optional) :
- Ensures a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens 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 absorption
• Soft when blended with cotton

Marie period 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 two sizes, choose the larger one. Periods often come with a bloated or sore stomach.
