The absorbency of dais period underwear depends on the model.
Each slip can hold the equivalent of 1–5 regular tampons of menstrual fluid.

dais period underwear protects you through a smart 4-layer system.

1. Transport layer – quickly directs moisture away from the body
   
2. Absorbent layer – safely stores fluid
   
3. Protective layer – prevents leaks
   
4. Comfort layer – keeps the underwear soft, breathable and comfortable against your skin
   

Our fast-absorbing membrane provides optimal protection against leaks – for a dry, fresh feeling all day. Maximum comfort and security for a worry-free period.

After wearing your period underwear, it’s best to rinse it by hand until the water runs clear.

You can then machine wash it at 40°C together with your other laundry.

For best results, use a laundry bag for your dais panties and avoid fabric softener, as it can affect the absorbency of the fibers.

And please don’t tumble dry them – instead, hang them to air dry, so you can enjoy your period underwear for as long as possible.

We recommend to change your dais underwear once to twice per day. For example, before bed and in the morning when you wake up. If you have a heavy flow, you might need to change mid way through the day too. You will know when to change them as it will start to feel wet on the outer layer as the underwear is unable to absorb more liquid.

dais underwear do not feel like diapers- in fact they are very thin and are closer to normal everyday underwear than they are like diapers. They also do not make horrible sounds under the clothes, and cannot be seen when wearing under your normal clothes thanks to the seamless technology.

dais period underwear is designed with a multi-layer system.
The top layer quickly draws moisture away from the body into the absorbent core, so you stay feeling dry. If the underwear starts to feel damp over time, it means it has reached its capacity and it’s time to change.

dais underwear are a great replacement for one time use products. Did you know that during a lifetime women can use up to 15,000 pads or tampons! With dais underwear you can save up to 98% waste.

You’ll hardly notice a difference. The absorbent lining in our period underwear is only 2 mm thin and made from organic cotton, making it soft, comfortable, and breathable.

The slightly wider lining in the intimate area provides a secure fit that gently hugs your skin without causing irritation.

So you don’t have to worry about leaks, discomfort, or visible lines under your clothes.

That depends on how heavy your flow is and how often you plan to do laundry.

Many of our customers find that 3 to 6 pairs are enough to get them through their cycle.

Some also like to combine period underwear with other products such as tampons or a menstrual cup.

Our tip: start with a few styles in different absorbencies and see what works best for you.

Absolutely. Period underwear is designed to be worn anywhere – whether you’re on the go, working out, or sleeping.

It fits comfortably, stays in place, and keeps you protected for up to 12 hours.

When Eva and Grace founded dais, they designed the underwear to perfectly fit an active and busy lifestyle.

dais underwear is a more sustainable alternative to single-use products.

Our period underwear is durable, reusable and therefore more resource-friendly compared to disposable products such as pads, tampons or liners.

For our technology to work, we do need to use some synthetic materials. Nylon-based styles, for example, contain more plastic because nylon is a textile made from oil.

To take responsibility for the plastics we do use, we partner with CleanHub: for every gram of plastic in our underwear, the equivalent amount of polluting plastic is collected from the environment.

dais underwear is currently produced in Asia by carefully selected partners.
All production sites are regularly and independently audited to ensure high standards of quality, safety and fairness.

dais absorbent underwear
work based on a 4-layer technology in which plastic is utilized to ensure water and leak proofing- a commonly used technology for this product type.Working together with CleanHub, dais has been able to
neutralize the use of plastic in their underwear, making them the world’s first plastic neutral period underwear. Through this initiative, dais enables the fast collection and recovery of ocean bound plastic waste which supports clean environments and creates sustainable jobs in the global south.

No, we do not use biocides in any of our absorbent underwear. We have experience of working with biocides in the past and so became aware of potential adverse consequences of using them. We therefore recommend some alternatives which we are more comfortable using to keep our underwear clean and maintain their condition over their lifetime.

We recommend to wash our underwear at a more eco-friendly maximum of 40 degrees celcius. To ensure bacteria and odours are properly handled there are a few things we recommend.

1. By using a liquid detergent rather than a powder there is a higher chance that the detergent is able to work as powders sometimes do not dissolve properly in a colder wash.

2. Most modern detergents are highly efficient even at colder temperatures however if you want to be sure that 99,9% of bacteria and viruses are killed you can use a laundry sanitizer. Simply purchase a bottle at your local shop and add as instructed to your wash. Please do not use any product containing bleach.

3. White vinegar (5%) is a great everyday disinfectant. Simply add half a cup to your machine wash.
