    Before the first use, we recommend that you wash the underwear to enhance the functionality of the absorbent layer (just like a towel).

    Step 1
    Use period underwear instead of pads, tampons or cups, or as a backup for extra protection.

    Step 2
    After use, rinse in cold water until it runs clear. Machine wash cold (30°) or by hand with a mild detergent. Do not use fabric softener or bleach. Hang to dry.

    Step 3
    Reuse and repeat – during the day and night!

    Designed in Denmark. Made in Portugal.   

    Materials

    Disposal
    The underwear: Most textiles can be recycled. The collected textiles are sorted and graded as natural, synthetic, and blended fabrics and will be used again.   

    The packaging: All our packaging is made from recycled and/or recyclable paper and cardboard. 

    Please make sure to dispose of the packaging in the appropriate bin, according to your local recycling regulations.

    We offer a full refund on your first pair of underwear, if it doesn’t work as promised. You can claim the guarantee within 60 days of receiving your order. Size exchanges are not possible for period underwear. Learn more.

    How long can I wear the AllMatters period underwear for?
    As long as your flow allows. Some can wear it for a full day, while others use it as a backup for a cup or tampon. We generally recommend you use them for 8-12 hours. They can also be used overnight and for spotting or discharge. The underwear itself lasts for years.     

    How many pairs do I need?
    We recommend that you have 3-4 pairs so you can change into a new pair after wearing them for 8-12 hours. Wash and dry the used ones before reusing.     

    How will I know they are full?
    You can tell by looking at the seams of the gusset. If you see blood at the seams or if the underwear feels wet, this is an indication that you should change them soon. As you start using them, you'll quickly get a sense of your flow and how long you can be leak-free for.     

    How much blood can it hold? 
    We provide underwear in two levels of absorbency: Light/moderate and Moderate/heavy. The Light/moderate absorbency option can hold the equivalent of 1-2 tampons worth of fluid (approximately 10ml), while the Moderate/heavy absorbency option can hold 3-4 tampons worth. Choose the level that best suits your needs.

    Is it hygienic?
    Yes. The inner layer (made partly from merino wool) is naturally antibacterial and anti-odour. After use, you rinse out the absorbed blood in cold water and then hand wash cold with a mild detergent or machine wash cold (30°). After hanging to dry, they're ready to be used again.

    Bom investimento

    As cuecas menstruais são muito confortáveis. São absorventes mas ainda assim iriei adquirir o modelo com maior absorção para os dias de maior fluxo. O tecido é suave e fácil de lavar e secam relativamente rápido. Recomendo bastante para um conforto adicional.

    Cuecas menstruais

    Cumprem muito bem a sua função e são de boa qualidade. A única coisa que tenho a apontar é que as costuras não são nada confortáveis e irritam-me a pele… tenho muita pena por isso, porque de resto gosto imenso delas.

    Utilissimo

    Mi ci trovo benissimo, ne ho prese altre due apposta! Ho un ciclo MOLTO abbondante, quindi lo uso, per stare più tranquilla, sopra uno slip con un assorbente che così mi dura un giorno intero, sia la notte che il giorno, e in più con la coppetta.. finalmente non mi macchio più!

    Bløder igennem

    Jeg blødte igennem efter kun 2 timer selvom det var heavy trussen - derudover går man hele tiden med en våd følelse.
