Healthy underwear ensures you don’t experience any extra vaginal discharge. It also makes sure that the discharge you do have is properly absorbed. Oh Yaz underwear is made from skin- and allergy-friendly fabric that is both absorbent and moisture-regulating. All of our briefs are made from sustainable materials, fit perfectly, and look damn sexy!

And just for the record: underwear made of polyester, polyamide, nylon, and even cotton? Not healthy.

Good news, you don’t need much for this. To clean your vulva, all you need is water. Your vagina doesn’t need anything at all. Unlike your laundry, she’s self-cleaning, baby! Besides that, healthy underwear is a must. It prevents extra irritation and absorbs sweat and discharge.

Don’t let them talk you into buying other products! Panty liners shouldn't be necessary to absorb discharge, that’s your underwear's job. Why else would you wear it? By the way: panty liners disrupt your balance down under, which can cause irritation and vaginal itching.

So: break the vicious cycle and invest in thongs and briefs that are kind to your vagina.

The pH of your vulva gets disrupted by underwear made of polyester, polyamide, or nylon. The lack of breathability throws your vaginal balance off and can lead to irritation or even infections. It gets your coochie mad AF! An irritated vagina produces more discharge, meaning briefs made of polyester, polyamide, nylon, and other synthetic fabrics actually cause extra discharge, but they can’t absorb it. The result: more irritation. A vicious cycle you can say Bye Bye Bye (NSYNC Voice) to.

Unfortunately, they are quite common: 75% of women will experience one at least once. But just because it’s common doesn't mean we should consider it "normal" (like so many other female discomforts 🙄). So: no more taboos! At Oh Yaz, we talk openly and honestly about our vaginal health.

The truth is, there are solutions, and they are simpler than you think. Wash your vulva (= the outside) with water and wear healthy, breathable underwear. This is exactly why we created our underwear: to eliminate all those other "must-have" female hygiene products. They disrupt your vaginal balance. But your vagina knows exactly what to do. Leave her alone, that’s why she is a bit sour.

Actually, it’s your underwear's job to absorb vaginal discharge. So: panty liners? No, thanks! They disrupt your balance down under and cause extra irritation. Our advice: break that vicious cycle and invest in healthy briefs with great absorption. Trust us: you won't even need those liners anymore!

We get it: thongs are practical and sexy, but they can be sooo uncomfortable. We believe you shouldn’t have to settle for that. In fact, we go one step further: with Oh Yaz underwear, you’ll forget you’re even wearing a thong at all.

With extra fabric in all the right places, your thong stays in place perfectly. Our thongs have been extensively tested by women of all sizes. And yaz: we’re proud to say that many ladies who had sworn off thongs entirely, are falling in love with them all over again thanks to Oh Yaz!

Our briefs and thongs are made from EcoVero™, a fabric derived from wood and pulp (from sustainable forestry). Nearly all chemicals used during the production of EcoVero™ are recovered and reused. Compared to conventional viscose, the production of EcoVero™ generates 50% fewer emissions and requires half as much water and energy.

When you click on your size, you’ll see a model wearing the briefs or thong in that specific size. Our fabric has a beautiful stretch. Don't know which size to order? Our sizing is very flexible. So don’t overthink it: both sizes move with you, in every sense.

Absolutely! Our fabrics are stretchy and adapt to your changing body. Before, during, and after my own pregnancies (a 30 kg difference), I kept wearing my regular size and the exact same pairs. They don’t roll down or lose their shape, even after countless washes! It’s the ultimate proof of our flexible sizing 👌🏻

Handle with (self)care – just like you should treat yourself. Wash your Oh Yaz briefs and thongs at 40°C on a delicate cycle (low speed, max. 400 rpm). Use a mild detergent and place your underwear in a laundry bag. This protects your favourite pieces and makes them easier to fish out of the machine afterward. Let the underwear air dry (they are not dryer-safe). Find all care instructions on the box.

Would you like to return or exchange your order? Legally, hygiene products like underwear cannot be returned. To respect this, we can only accept returns where the packaging (the box) has not been opened yet. If your box is still sealed, we are happy to accept your return, even though it is technically not required. We do accept returns, but only under the condition that the box remains closed to ensure the underwear inside is unworn and unwashed. Our entire brand revolves around Vaginal Hygiene, so we naturally have to be very strict about this. If the box has been opened (which is logical if you want to try them on), unfortunately we can no longer take them back.
