What is period underwear?

Period underwear is an absorbent underwear which is made up of 4 layers of materials designed to soak up and store period blood while you wear them. The blood is then later washed out in the washing machine and the underwear is re-used. For this reason, reusable period underwear is an environmentally friendly alternative to other period products such as tampons and pads. dais offers period underwear in different shapes, sizes and materials so that everyone can find the perfect fit for their needs and wishes. All of dais period underwear can hold up to 4 tampons worth of blood, which is a lot! For most people this would be enough that the underwear can be worn the entire day without having to change.

How does period underwear work?

dais period underwear works on the basis of 4 layers, which are designed to quickly absorb, capture blood and store it. This ensures a dry feeling on the underwear all day long.

Layer 1: The first layer is the layer which is in contact with the intimate area. It is made of 95% organic cotton which makes it very soft, breathable, and absorbent. It works to quickly absorb period blood and transport the liquid to the next layer which helps you feel dry all day long.

Layer 2: The second layer is a bit like a super, super thin sponge however it is made out of a cotton and bamboo mix in all dais period underwear. It absorbs and stores the liquid for the entire day.

Layer 3: The third layer is like a waterproof lining ensuring that the period blood cannot leak out of the bottom on the underwear. dais period underwear additionally has leak proof edges which ensure that the underwear cannot leak out of the sides.

Layer 4: This is the final layer and the main layer of the underwear. Its main purpose is to cover you and make you feel comfortable whilst holding all of the elements of the underwear together. dais period underwear come in all different materials, sizes and shapes so that you can find the best one for you. If you like organic cotton, we recommend taking our Hipster cut. If you want a more modern cut and material, we recommend the Cheeky Nylon cut.

Do period underwear really work?

Do period underwear feel thick and like a diaper?

There is no rustling or noises like you have in a pad or a diaper and it is much thinner. dais period underwear make use of both natural and smart technology materials to achieve such a thin underwear with such a powerful absorbency.

How to clean period underwear?

dais period underwear is really easy to clean in 4 steps.

Step 1: Rinse with cold water. This ensures that the blood does not stain and stay in the material and that most of the blood is rinsed out before the product is put into the wash.

Step 2: Machine wash at an eco-friendly temperature of 40 °C (degrees Celsius). This not only saves you money and is more eco-friendly, but it ensures that all the layers stay the same shape and size and do not shrink, allowing you to use more underwear for the years to come. We recommend using a liquid detergent as powdered detergents sometimes struggle to dissolve at lower temperatures. We also recommend every once in a while, using laundry detergent to ensure that all bacteria is killed on the underwear.

Step 3: Air dry. Simply place on the laundry line or hang inside your home to dry.

Step 4: Reuse, repeat and leave the world a better place.   

How long can you wear period underwear?

You can wear dais period underwear for the whole day or night as it has enough absorbency as 4 tampons. However, if you have a very heavy cycle, you might have to change it a bit earlier, after 6-8 hours.

You can keep dais period underwear for years, especially if you occasionally use a laundry detergent as it will help to ensure there is no bacteria build up. This way, dais period underwear can be used for 3-5 years or until there is any natural wear and tear.

Do you wear pads with period underwear?

No, you do not need to wear pads with dais period underwear as they are a direct replacement for pads. What is possible is to combine the period underwear with other sanitary products such as menstrual cups or tampons. We do not recommend this as we prefer to completely replace one time use products, however if you have a heavy cycle or are just looking for an extra security for leaks, this is the perfect product for you.
