product details

Want a style that radiates as much positive energy as you do? Your favorite ooia Hipster now available in bright red.

The ooia period underwear Hipster holds up to three tampons of liquid while feeling completely dry. This makes it ideal for your medium to heavy menstrual period days. Plus, the ooia Hipster is washable, making it reusable. You can wear the ooia Hipster alone or as a back-up to other period products. Plus, ooia is great if you're waiting for your period but aren't sure exactly when it will start.

If the 158 size is too small for you, feel free to try the 32/34 adult ooias 

ooias are produced ethically and ecologically fair in Portugal, Lithuania and Croatia with fabrics from Europe.

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


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 soaks up the liquid, and keeps it from leaking out. 

  1. The layer closest to the body is made out 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 consists of specialized fibers that absorb moisture lvery quickly. This layer is also equipped with an anti-bacterial 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 your ooia, it is best to wash it by hand in cold water.

    Then you can put it into a laundry net and into the washing machine and wash it at 40 degrees ideally in the easy-care wash cycle - you can also do this along with other dark laundry.

    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 a no-go, just hang ooia on the clothesline and it will soon be ready fro wear again.

    If you treat your ooia 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.

    bacteria inhibition

    Because your health is our top priority, we've sought the opinion of gynecologists on the requirements for bacterial growth inhibition. 

    These gynecologists confirm that it is fundamentally important that period underwear inhibits bacteria growth - 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 in terms of health.

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

    The Hohenstein Institute carried out elaborate testing on our ooias to ensure its antibacterial activity.

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

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


    ooia is made out 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).

    Some raw materials which enter our fabrics cannot be sourced from Europe, as this is not possible for climatic reasons.

    material composition:

    Upper fabric: 93% cotton, 7% spandex

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

    Mid-layer: 80% cotton, 20% polyester

    Membrane: 100% polyester backing, 100% polyurethane membrane

    bacteria inhibition

    Your health is our top priority.

    Gynecologists confirm that a bacteria inhibiting coating on period underwear is indispensable.

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

    It is very important to us that we communicate transparently in this regard. 

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

    No nano particles are used.
