AWWA period-proof underwear look and feel just like your normal underwear, but can hold and absorb up to five regular pads or tampons worth of blood.

Our rigorously tested NZ designed period underwear features 4 layers to absorb and hold your period blood, discharge or bladder leakage: 

• a super-absorbent layer to hold and absorb your flow

• anti-microbial and moisture wicking technology to keep you dry and feeling fresh

• a soft organic cotton layer closest to your skin, designed to draw moisture away fast

• a leak-resistant barrier to prevent any leakage

This depends on you and your flow — you know your body best. AWWA underwear can be used instead of other menstrual products, or for those with a heavy flow you may choose to wear them as a backup to your tampon or cup. We suggest you test your own limits.

We have used the latest innovations in fabrics to prevent odour and dampness. The anti-microbial layer fights bacteria and odours, and the moisture wicking cotton quickly draws moisture away from your skin, keeping you dry.

AWWA underwear has been rigorously tested. Depending on the style you purchase they can hold between 1 -5 regular pads/tampons worth of blood.

They look and feel just like your normal underwear. We’re not kidding! In fact some would say they’re even more comfortable than your normal underwear.

The layer closest to your skin is 95% organic cotton, 5% spandex. Other fabrics used on our Eva Brief, Frankie Brief and Skye High are recycled nylon and spandex. They shouldn’t irritate even sensitive skin. Our Boxer Brief is made from Tencel which is a brand of lyocell and modal fibres that is made from sustainably sourced wood!

We are committed to revolutionising periods for menstruators while doing everything we can to care for you and Papatūānuku, our planet. We would never intentionally add anything harmful to our period underwear, including PFAS. 

Fabrics used in the production of our underwear have been tested by Bureauveritas in China. They test for Fluorine, as this is the key detection which would indicate the presence of PFAS (as there are thousands of different variants of PFAS).  

The test results came back as ND (None detected). NOTE: A test result under 10 ppm (parts per million) is considered “ND”. If PFAS are intentionally added, the quantities will be much higher!

Of course! AWWA underwear is also suitable for spotting and minor bladder weakness (pregnant and older women rejoice!) You might even love them so much that you decide to wear them every day. You do you.

Yes! For pregnancy, AWWA are great for light bladder leakage and discharge. For postpartum, generally we advise to wait the first few days after giving birth as your discharge will include blood, clots and lochia.  Clots and lochia contain solid and mucousy discharge and will (similar to the way a pad works) not allow the gusset to absorb effectively. 

Firstly, make sure you measure yourself using our size guide. Your hip measurement is the most important one when trying to find the right size underwear. For some of our styles it's also helpful to know your waist measurement.

Absolutely! Our underwear can be worn by all people who get their periods. Discover our curated teen period underwear range. 

AWWA last up to two years following our care instructions, as long as you haven't used a dryer or fabric softener during that time. These ruin the membrane that keeps them leak proof. You know when it's time to replace your period undies when you notice leaking through to the outer side of our undies when usually this wouldn't happen, meaning the membrane has now worn.


Yes! We recommend giving your AWWA a quick rinse and a machine wash before wearing on your ikura. This step is very important for activating the absorbency technologies within the briefs.

We recommend rinsing thoroughly by hand first, then pop in a cold wash with your other clothes and line dry. DO NOT use fabric softener as it can block and prevent the moisture wicking and anti-microbial technologies from working. 

This can be due to your AWWA not being rinsed properly after use.  Try washing them again with a hygiene rinse to see if that helps. If you don't have access to a hygiene rinse or prefer something more natural you can try soaking them in the sink or a clean tub with one cup of white vinegar and some cold water. Leave them to soak for about 15 to 30 minutes, then clean in the washing machine. You can add a little white vinegar to the wash too, if you think they need it. This will remove build-up and get rid of the odour. 

Make sure to fully rinse out your undies immediately following wear (especially if you might not be putting them in the washing machine for a day or two).

To ensure that they are completely dry all the way through before wearing again you are able to hang them in the hot water cupboard, however natural sunlight is best for your AWWA.

We do not recommend putting your AWWA into the dryer, as you are unable to control the temperature of a dryer once the machine is running, even on a low heat setting it is still unknown what that temperature could be. Excessive heat can compromise the leak proof layer resulting in leakage.
