What's to love about our Teen Confidence Bundle (Black Friday Exclusive - Save 30%)?
When your undies arrive, try them on over your regular, clean underwear before use to check the fit. Make sure to give them a wash before your first wear to improve the absorption performance.
Then to use the undies, simply wear them like you would with any of your other underwear.
How long you wear your underwear for will come down to personal preference and your flow. We recommend changing every 6-12 hours.
Washing period undies and period bikinis/ swimwear is simple and hassle-free.
They can be machine-washed (we recommend using a garment bag, cold water and liquid natural detergent), and then line-dried for best results.
We do recommend rinsing them well prior to popping them in the machine, however this isn't necessary.
Think your individual decisions won't make a difference?
Well, did you know more than 12 BILLION pads and tampons are thrown out every year worldwide? Let's break this down even further to see the impact you CAN make - the average woman alone uses 11,000 pads, tampons and panty liners in their lifetime. That’s a lot of landfill! It's time to make the switch to Eco Period, you won't look back.
IS IT YOUR FIRST TIME TRYING REUSABLE PERIOD CARE?
Once you start, you'll never go back to traditional single-use period care products again!
-
Eco Period Australia underwear absorb your period.
Every pair is made with our signature technology that's odor-controlling, super-absorbent, and leak-resistant. This 4 layer technology works together to do it’s thing (aka keep you fresh and dry). Take a look at our How It Works page to learn more.
-
Yes, our period underwear has been designed to be worn alone, with no tampons or pads required. If you wish to wear a menstrual eco cup as well, this can extend the wear time of your eco briefs.
Also the length of time you can wear each pair depends on your flow.
As a general rule, we recommend choosing heavy or super absorbency for your heavy flow days and moderate or light for your lighter days.
-
This comes down to personal preference and your flow, however you can wear a pair of undies for as long as 24 hours. We find most of our customers like to change every 8-16 hours. There's no right or wrong here!
-
Our range of period underwear range from Super > Light. Scroll down to check out our Absorbency Guide here to decide which level is right for you.
-
Firstly, work out how many days of your cycle are heavy and moderate/light. Then, you can calculate the number of briefs you will need using this guide:
Heavy flow days:
- Within a 24 hour period, we'd recommend changing 2-3 times.
- Suggested change times - morning, midday (optional if your flow is heavy) and at the end of the day.
Moderate/light flow days:
- Within a 24 hour period, we'd recommend changing 1-2 times.
- Suggested change times - morning and at the end of the day.
So you can allow ample time for washing + drying, we suggest buying double the amount you calculate above, so you're never caught out without a clean pair to wear!
-
If you use period cups or pads you might not need as many pairs of period underwear.
Browse our collection of eco-pads and menstrual cups to grow your eco-friendly period solutions.
If you're often on the move and wish to change your underwear, we recommend getting a wetbag for your used underwear to store them before you're able to wash them.

SUPER
●●●●● 30-60ml
The lining is thicker and extends to the back waist seam, so it covers you for overnights.
HEAVY
●●●●○ 25-40ml
Choose Heavy absorbency if you have a heavy flow or for your heavy flow days or for moderate incontinence.. The lining extends to the back waist seam, so it covers you for overnights or when laying down on your side and back.
MODERATE/HEAVY
●●●○○ 20-30ml
Perfect to use if your flow is moderate, so think 3rd or 4th day of your period. Also for light to moderate incontinence leaks. These undies will also cover you at night as the leakproof lining extends up to the back waist seam (a thinner layer than the heavy absorbency).
MODERATE
●●○○○ 15-20ml
Choose Moderate absorbency for day-time wear, active wear and for when you just don't need that extra panel of protection up the back. Suitable for flows from 15-25 ml. The lining is generally a little thinner too, so does not feel bulky.
LIGHT
●○○○○ 10-15ml
If your flow is light, or you are using as a backup, choose light absorbency. This will provide a leakproof function and some absorbency as a backup.
