What are menstrual underwear?

Use of menstrual underwear is growing. This is to be expected, as they are very comfortable and all-round a better period solution than throw-away products. They trap menstrual fluids and smells and in case you are wondering: they are absolutely nothing like nappies!

Perfect for medium or light menstrual flow.

.Period underwear is made up of multiple layers .

Menstrual briefs are made up of different textiles. The combination of technical textiles work in sync to enhance your menstrual experience. To ensure their functionality, each manufacturer uses various technical materials that change from panties to panties. 

-Top layer: commonly cotton, modal, or similar. This is very soft and comfortable. In direct contact with your most delicate skin and absorbs by capillarity your menstrual blood ensuring the comfort of the brief. 

- Middle layer: composed of absorbent technical material that blocks the flow and ensures that you remain odor-free and damp-free. 

- Bottom layer: Technical material that confers some impermeability preventing leaks. This layer is also breathable in an extra effort to keep the panties dry, and so you don't have to worry about your period and go about your day.

They can be worn all day or night without causing irritation. They can also be used to complement the menstrual cup throughout your period.

There are some formats that absorb abundant menstrual flow and are definitely worth trying if you do not want or cannot use the menstrual cup.

Unlike with the menstrual cup there are not many brand options.

Watch-out: some webpages offer menstrual underwear with specific characteristics, for example, made with ecological bamboo fibre and if you purchase their products, they are not what was promised. These products take a long time to arrive also as they are imported directly and have no clear provenance. You will find none of these products at Redpanti.
