Why Wear a Period G-string? Won’t it leak?
If you’re comfortable wearing a G-string normally, then you’ll enjoy the lightweight feeling of period thongs, which are good for those days when you’re expecting your period to come or for the last days of your cycle, if you experience spotting, or light discharge. They are fantastic for underneath your gym tights and active wear for no VPL confidence. The period g-string can also be worn as a backup to tampons or a menstrual cup.
Skin contact layer of the inner gusset is 95% cotton/5% elastane. Outer fabric is 78% nylon/ 22% elastane.

ECO-FRIENDLY PRODUCTION
Fabric Composition: Inner fabric: 95% cotton 5% elastane (skin contact layer of gusset)/ 100% Polyester/ Breatahable TPU (hidden layers)/ Outer: 78% Nylon, 22% elastane.
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.
Step 1 Wash your Eco Period underwear before wearing / using them. This activates the EcoTech and primes it for use.
Step 2, After wearing, rinse in cold water until the blood/ fluids are mostly removed. You can do this in the shower to save water, but just do it before the water heats up past 30 degrees, as heat will set stains into the fabrics.
Step 3. Pop your undies into a delicates wash bag and into the washing machine on a cold wash. Use a liquid natural detergent.
No fabric softeners.
Step 4. Hang dry on the line outside. Line drying is best as it is kinder to the fabrics. Just don't leave them out on the line for days.
Eco Period underwear should NEVER:
Be cleansed with harsh detergents (these abrade and break down clothes which shortens their effectiveness and lifespan)
Be cleansed with fabric softeners (it's like fabric cholesterol and blocks the pathways in the fabric through which the liquid travels)
Be bleached (bleach kills everything, need we say more)
Be dry cleaned (putting the products into such a harsh environment with or without the added chemicals is bad)
Be washed in very hot water (heat breaks down the fibres and natural compounds that make these products so effective.
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.

As a gymnast I have forever struggled with bladder leaks from the impact of flipping around, and I know I’m not alone!
Over the last couple month I’ve been on the hunt for the best absorbent/period underwear to train in and I’ve found a winner in the Invisi Seamless Range.
My go to is the Invisi Seamless G.
I had never been a big fan of G Strings but these are a game changer for me.
They are perfect for light period days, sweat absorbency and those cheeky bladder leaks that gymnasts are all too familiar with! With that added bonus of no visible seam lines.
The coverage is amazing allowing me to bend, flip and stretch comfortably without them moving out of place.
My favourite feature is how the absorbency layer goes right up to the waistband at the back for added protection.
They also allow me to tumble comfortably knowing I have the protection of the absorbency layer.
Amazing product. Lightweight, slim and streamlined. I really like them as they're flattering.
These fit true to size and are great for very light flow days.
Great product!
I love the seamless g-string. It fits beautifully and feels luxurious. Also love the customer service I received when ordering online. I was able to make an exchange with no hassle at all. Definitely recommend this company and their products.
OMG, these are definitely a game changer for me. I prefer g-strings as I hate having ‘undie line’ showing. These give me the protection I need without the bulk. I will be purchasing more for sure.
My favourites
very comfortable.
Made more durable
Pretty comfortable, no leaks.
Super comfy! Higher rise than my usual g-strings, used the sizing chart for purchase and they are spot on :)
I love these! I prefer g-strings when not on my period and this is perfect for the day before or those couple of days after when you know you might spot! A large amount of coverage for a g-string too!
Abso-bloody-lutely love these! They are super comfy and fit really well. I feel confident to wear tight workout clothes and know nothing will leak. Highly recommend :)
Absolutely love the leafy printed seamless g's they are my favourite and i have more of these than any others :)
Really comfy, look great sizimg is right on, postage is quick, great company and great product
I loved the G string I bought. Fitted well and comfortable but was disappointed when I could not buy another as was sold out
Think your individual decisions won't make a difference? Think again.
The average women uses 11,000 pads, tampons and pantyliners in their lifetime.
That's a lot of landfill! It's time to make the switch to Eco Period Australia - 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!
Check out our Know Your Flow page for more guidance.
-
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.
We recommended washing your undies in a wash bag to protect garments in the washing machine and prolong their lifespan.
