About the product

An easier start to your period routine, with a comfort you may still choose later on. You put them on like regular underwear, without having to learn a technique for insertion or attaching.

The hipster fit and stretchy fabric follow your body's movements – at school, at the office or in your free time. Hemp and organic cotton form the base of the gusset layer and feel soft.

Absorbency for moderate and heavy flow, with extra coverage at the back.

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

Can I use IDA from my first period?

Yes, if the size and absorbency suit your needs. They are worn like regular underwear. At first, check more often and bring an extra pair until you know your rhythm.

Is IDA only for teens?

No. It can also be worn by adult women who prefer the hipster fit. You choose based on measurements, flow and comfort – not just age.

Do I also need to use a pad?

Not necessarily. IDA can be worn on its own if the absorbency is enough for your flow between changes. You can combine different types of protection according to your needs and preferences.

How do I know when I need to change?

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.

How do I prepare for a school day?

Bring a clean pair and a waterproof bag for the used pair. Check during breaks whether you need to change. When you get home, take the pair out of the bag and follow the care instructions.

Can I wear them for sport?

You can wear them for physical activity if they fit your body well and you feel comfortable. Check before and after the activity whether you need to change. For swimming, choose a period product designed for water.

How do I choose a size for a teen?

Measure waist and hips and use the product's guide. Age is only a guide; the underwear should sit close to the body without being tight or leaving large gaps at the gusset.

How many pairs should I use?

You can start with one pair to check the fit. For regular use, you need enough pairs for your changes and for the time it takes to wash and dry them, plus an extra pair when you're out.
