product details

The String Seamless in beige by ooia gives you security, comfort and reliability during the light days of your period. The String is specially designed to give you a feeling of freedom and confidence without compromising on your choice of underwear.

The discreet thong is seamless and fits your body perfectly without showing. The soft material gives you a comfortable feel, while the leak-proof membrane holds up to a tampon's worth of fluid and feels completely dry. What's more, the ooia thong is washable and therefore reusable. You can wear the period thong on its own when bleeding is light or as a back-up to other period products on heavier days. The inside of our String Seamless beige is made out of the finest black merino wool - just as in our black models.

At ooia, we believe that every body type is unique and deserves special products. That's why we created the Seamless Period Thong to give everyone the opportunity to feel unique during their period.

ooias are sewn exclusively with fabrics from Europe in sewing factories in Portugal, Lithuania and Croatia, which produce ethically and ecologically fair.

Our model Toni wears a size 36 and our model Lama wears a size 44-46.

With your purchase you support organizations that promote female empowerment with their projects - here to learn more.

We use silver chloride to inhibit bacteria and odors. The skin compatibility has been confirmed by OEKO-TEX. EU Regulation No. 528/2012: Biocidal active ingredient is silver chloride. No nanoparticles are used.

magic membrane system

An ooia period underwear is as beautiful and comfortable as your favorite underwear, but it can do much more: it has an integrated membrane system in the crotch that draws the liquid away from you, absorbs it and prevents it from leaking.

still questions?

How many ooias do I need for a period?

The ooia period underwear is designed to hold 1-6 tampons or 10-30ml of fluid, depending on the model.

How many and when you use ooia period panties depends entirely on your needs - your preferences, your plans, the intensity of your bleeding, and many other factors. To completely cover one period, you will need about 5 ooia period panties - assuming you wear one at night, one during the day, and wash the used panties after two days.

Can I avoid using other menstrual products with my ooia?

The ooia period underwear is designed to hold 1-6 tampons or 10-30ml of fluid, depending on the model. How many and when you use ooia period panties depends on your needs - your preferences, your plans, the intensity of your bleeding, and many other factors. There is no one size fits all solution. If your period is light to medium, you can most likely use ooia period underwear without additional period products. If you bleed very heavily, you may want to use additional protection (tampon, cup).

How long can I wear my ooia?

If you treat ooia period underwear well, it will retain its full antibacterial effectiveness for around 2 years . After that, you can of course continue to use it as "normal" underwear - although studies show that underwear is rarely used for longer than two years. But we are happy if ooia is used for longer.
