The AllMatters period underwear is your reusable, comfortable, and leak-free period solution. It feels like regular underwear but has built-in layers that serve different purposes – from absorbing your flow to keeping you dry and odour-free and avoiding stains on your clothes.

Fit: Flattering high cut legs and sits just on the hip. Mousseline stretch trim at the waist and legs.

  • Breathable and comfortable
  • Designed to last, use again and again
  • Made from sustainable materials, TENCEL™ and VEOCEL™
  • Can hold 1-2 tampons worth of flow
  • A leak-free period solution, day and night
  • Doesn’t contain PFAS or harmful substances

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 Sri Lanka.   

Materials 
Body: 94% TENCEL™ Lyocell, 6% elastane

Absorbent core: 100% VEOCEL™ Viscose

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?
The equivalent of 1-2 regular tampons worth of blood (10ml).

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°). Afte hanging to dry, they're ready to be used again.

God ide, mega bløde - men jeg fik svamp af trusserne, da mit underliv ikke kunne ånde

Jeg købte 3 par, og ville have "den rigtige" oplevelse ved sidste mens., så jeg havde kun dem på. Normalt burger jeg stofbind og kop. Denne gang var det altså kun trusserne og jeg har nu fået svamp, hvilket jeg aldrig har haft eller døjet med i mit liv før.
Jeg vaskede alle trusserne inden brug efter anvisningen, men jeg tror trusserne er lavet lidt for "sikre" således at intet kan slippe ud - men det gør på den anden side også, at underlivet ikke kan ånde - i hvert fald ikke mit. Øv øv, og jeg går tilbage til det jeg plejer at bruge. Det kan være at trusserne virker for andre?
