An ooia Period Panty is as beautiful and comfortable as your favorite underwear, but it can do so much more: it has a built-in membrane system in the crotch that pulls liquid away from you, soaks it up, and keeps it from leaking out. 

  1. The body next layer is made of soft merino wool. It quickly wicks moisture away from the body. So you feel dry at all times. In addition, it is equipped with a bacteria-inhibiting agent, so that  no bacteria can multiply and no unpleasant odor develops. More info: click here
  1. The middle layer is made of specialized fibers that absorb moisture like a sponge at lightning speed. This layer is also equipped with a bacteria-inhibiting agent. More info: click here.
  1. The outermost layer is a liquid-impermeable membrane that doesn't let any liquid through to the outside, protecting you from leakage. In addition, this layer - just like all the other layers - is breathable and thus ensures that you do not sweat.


    Wash your ooia once before the first use.

    After wearing you wash ooia best with cold water by hand in cold water

    Then it goes in the laundry net off in the machine at 40 degrees easy-care wash cycle - gladly also together with other dark laundry - she will not wear any damage, really!

    Please don't wash your ooia with full strength detergent, as this is too aggressive for the wool. Instead, ideally use wool detergent.

    Please do not use bleach or fabric softener, as this will reduce the effectiveness of ooia.

    Please also do not dry clean - but who takes their underpants to the dry cleaners?

    Ironing is also taboo, just hang ooia on the clothesline normally and it will soon be ready for use again.

    If you treat ooia this well, it will retain its full bacteria-inhibiting effectiveness for about 2 years. After that, of course, you can still continue to use them as "normal" underpants.

    bacterial Inhibition

    We sought the opinion of gynecologists on the requirements for inhibiting bacterial growth because your health is our top priority. 

    These gynecologists confirm to us that it's fundamentally important that period underwear inhibits bacteria from growing - and that high-quality, tested fabrics are used to do so.

    Our membrane system has bacteria-inhibiting properties at key points -so that bacteria can neither multiply nor develop unpleasant odors. Our active ingredient silver chloride is tested under the strictest conditions and may be used in Germany in accordance with Article 89 of the Biocide Ordinance in conjunction with Section 28 (8) of the Chemicals Act. It goes without saying that we do not use any nano-active ingredients that are controversial from a health point of view.

    The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.

    We had the Hohenstein Institute perform an elaborate testing procedure on ooia to ensure its antibacterial activity.

    The Hohenstein Institute is a very renowned German textile testing and research institute that awards various seals.

    Incredible, but ooia is the only period underwear in the world whose function is certified - we are proud of that!


    ooia is made of carefully selected, specialized fabrics made in Europe. The ooia hipster is certified and tested for harmful substances according to STANDARD 100 by OEKO-TEX® [21.0.46579 HOHENSTEIN HTTI]. Thus, the ooia hipster is certified skin-friendly and harmless to health.

    In addition, our wool comes from merino sheep that are treated fairly (mulesing free).

    The raw materials for our materials do not all come from Europe, as this is not even possible for climatic reasons.

    material composition:

    Upper fabric: 93% cotton, 7% spandex

    Lining: 100% wool (merino wool: mulesing - free)

    Mid-layer: 40% cotton, 20% polyester

    Membrane: 100% polyester backing, 100% polyurethane membrane

    bacteria inhibition

    Your health is our top priority

    Gynecologists* confirm to us that a bacteria-inhibiting coating on period underwear is essential.

    This prevents odors and the multiplication of pathogens.

    At ooia, we are the only period underwear brand in the world to have this effect certified - by the renowned Hohenstein Institute! Our active ingredient silver chloride is tested under the strictest conditions and may be used in Germany in accordance with Article 89 of the Biocide Ordinance in conjunction with Section 28 (8) of the Chemicals Act. Silver has been used for centuries to protect against diseases. Already in ancient Greece and Rome it was used to disinfect water.

    The anti-bacterial effect of silver chloride takes place directly in the fiber.

    We attach particular importance to communicating transparently here. 

    EU Regulation No 528/2012: biocidal active substances is silver chloride

    Nano particles are not used
