Natural Menstrual Thong - Menstrual Underwear

The black menstrual thong is a menstrual thong. The thong resembles a traditional women's underwear but is designed to handle menstruation. Ideally for light-flow days.

Menstrual thong: Discreet lining in natural fibers

• playing the role of an ultra-soft permanently integrated undershield inside
• longer at the front and back than standard sewing templates to ensure perfect protection during your light flow or when used alongside your menstrual cup
• offered in 2 color choices:
• Natural: unbleached and untreated, for sensitive or infection-prone skin. Also a good choice if you like to visually track your menstrual flow.
• Black: for easier maintenance.

- A fine thickness 100% PUL : a breathable, waterproof fabric that makes
your panties invincible to any leak that would try to get through them.

Wearing the Marie Fil menstrual underwear means choosing to be comfortable and feel good in
our skin, whether menstruating or not. And together, now more than ever, we are doing good
gesture for the environment. 💚

Black menstrual thong

The black menstrual thong is underwear as shown in the main photo, made with
love in Quebec, for real (hi to my seamstresses Nadia, Marie-Ève and Mégane 💚)

The panties:

Composition:
95% cotton
+
5% elastane
=
100% comfortable

The lining: what touches your most sensitive area

Absorption level: 340 GSM (grams/square meter)
(This is my little geeky side that wants to point it out just because it’s the kind of thing)
that I find fun to know. Concretely, it's equivalent to an under-protector, version
deluxe)

Composition:
45% hemp*
+
55% organic cotton
=
100% natural

* Hemp is so much the future for the environment. Its processing requires
very little water and no chemicals.

It's simple, he's got it all going for him:

• antibacterial (goodbye bad odors)
• hypoallergenic (no more irritation or itching)
• top of the class in terms of absorption
• blended with cotton, it’s a truly gentle match for the skin

Size and exchange:

Buying panties online isn't easy. You never know if the fit on
will be fine for us. I understand you.

To order the correct size, measure your hips above the buttocks,
with the help of a measuring gallon that will be positioned so that it is parallel
on the floor. If you hesitate between two sizes, choose the larger one.

If the panties still don't fit despite this precaution, they can be exchanged
according to the returns and exchanges policy and in compliance with all the
the following conditions:

• The underwear must not have been worn without another garment underneath during try-on.
• It must not have been washed.
• She must be returned in the same condition as the panties were sent to you.
