How did we calculate?

*Scenario with the same pairs used for two years, without extra purchases and with constant costs. It does not guarantee lifespan or savings. The use and cost of the remaining products fall proportionally with the chosen percentage; absorbency is not equated. Adjust the percentage if the chosen pairs do not cover the desired use.

Frequently asked questions

Everything you want to know before you choose

Is it right for me if it's my first time trying period underwear?

Yes, the hipster fit is worn like regular underwear. Start on a day when you can easily check how they work and change pairs as needed.

Can I wear them without a pad or tampon?

Yes, if the absorbency is enough for your flow between changes. At first, check the absorbent area more often to find your changing rhythm.

How do I know when to change them?

Change pairs if you feel damp for a longer time, or if you notice the fluid is no longer absorbed as well. Don't wait for the maximum wear time if you need to change sooner.

Can I wear them at school or at work?

Yes. For changes away from home, you can bring a clean pair and a waterproof bag for the used pair. Take the pair out of the bag and wash it when you get home.

Can I sleep in IDA period underwear?

Yes, if the absorbency matches your flow while you sleep. Put on a clean pair before going to bed, and keep changing at night if you need to.

Do all IDA variants have the same composition?

No. The materials can vary between colours and variants. See the Technology section for the selected product; the composition on this page applies to IDA Black.

How do I choose my size if I already wear another FemiEko model?

Check your waist and hips in the guide for IDA Black. The same size can fit differently from model to model, depending on the cut.

How long do they take to dry?

The time depends on the temperature, ventilation and humidity in the room. Let the pair dry completely before using it again, and have other pairs ready while it dries.
