How to wash

Period knickers can be easily washed in 3 simple steps:

First, rinse the period undies in water until there’s no blood coming out. If there are any stains, use a neutral soap.

Second, wash them in the washing machine on a delicate cycle.

Last, air dry if possible. 

Tip: Don’t use fabric softeners or bleach and do not dry the period undies in the dryer. This will decrease its lifespan, affecting its proper functioning.


Disposable pads, tampons and pantyliners are one of the largest sources of plastic pollution in the world. 

We may use between 10,000 and 15,000 disposable products during our fertile lives.

Sustainable alternatives such as period knickers completely replace these disposable products. Helping to reduce the negative impact that disposables have on the environment.

  • Super comfy

    We have several pairs from Ecowoman and these are our favorites. They are super thin and don't look like we are wearing anything. They are cute and comfortable.✨

  • The best I've ever tried

    Super happy with my menstrual thongs. They are soft and super comfortable. And after-sell service is amazing!

  • I LOVE them!

    I'm very happy. It's the second time I buy them, they arrive in a few days and my daughter doesn't want to wear anything else!

  • Amazing customer support

    The best purchase I have ever made. I bought them for my daughter, it was her first time with her period. I was able to make her feel comfortable and secure. They absorb a lot, which is great because they don't let them go to the bathroom during class. I will definitely recommend them to other moms and will buy more from her in the future.

    Easily the best discovery I could have made in years, I feel total freedom!

Non pienamente soddisfatta

Ho provato a dare un'occasione alle mutande mestruali, vuoi perché a livello economico sono convenienti, vuoi perché anche a livello ecologico sono in linea con la mia etica.
Purtroppo, però, con queste mutande non mi sono trovata bene. Avendo un flusso abbastanza abbondante per almeno 2 giorni su 5, ho preso quelle che facevano al caso mio. Non sono state all'altezza di contenere molto, tant'è che dopo nemmeno due ore ho iniziato a sentirmi bagnata lungo le gambe e così era, effettivamente: le mutande non hanno retto. Ero fuori casa ed è stato molto invalidante oltre che fonte di disagio.
Avendole comprate, non mi sento di buttarle, perciò le uso solo in casa, evitando di metterle, però, nei due giorni più intensi.

Comode e traspiranti, unica pecca (che non compromette l'ottima funzione) poca cura nelle cuciture

o m foi um pouco largo. devia ter vindo o s.

Recomendo super 💜

Estou apaixonada pelas cuecas da Ecowoman, realmente mudaram totalmente minha rotina. Eu sofria muito com os pensos e tampões. Quando chegava meu período já ficava super ansiosa e com medo de passar constrangimento. Agora tudo mudou, me sinto livre e não preciso mais ficar me preocupando se vou ter vazamento, e ainda nem toquei na questão do conforto. É incrível porque agora não preciso mais mudar minha rotina por causa do período. Além de todas essas qualidades, fora a economia que tive no mês, é incrível. Estou amando!💜

Bequem und sicher

Meine Tochter trägt die Unterhosen gerne und ist glücklich, dass sie keine Binden mehr benutzen muss. Es fühlt sich viel angenehmer an als mit Binden, die Hose sitzt sehr gut.
