Menstrual underwear made in Quebec
Discrete lining in natural fibers
A lining is already present in the menstrual panties to create a natural barrier for the underwear. Although insufficient without a menstrual insert, it helps prevent surprises. The lining acts as a soft protector integrated 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 (unbleached natural shade): for sensitive or infection-prone skin, allowing menstrual flow to be seen. Black: For easier maintenance since persistent stains are not visible.
Breathable and waterproof barrier inside the period underwear
A breathable, waterproof barrier sewn into 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 it.
Light or heavy flow for a period panty?
The menstrual underwear adapts well to all flows. For added comfort, women with a heavy flow may prefer wearing a Diva cup or of a menstrual discFor a light to medium flow, the period underwear alone is sufficient for daytime use. An insert also lets you change only the liner 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) :
- Ensure a double absorbent and waterproof protection thanks to its composition identical to the gusset of the menstrual underwear.
- Fastens with snap buttons (ultra-thin, you won't even feel them, we promise!), to stay securely in place no matter the activity.
- Interchangeable as many times as you want throughout your menstrual flow.
