What Are Period Undies?

Period undies Australia or period knickers Australia, depending on what you want to call them, look like normal underwear but have been designed to absorb your menstrual flow. The gusset is not heavy and bulky like a pad. You can use period underwear on its own to absorb your period or if your flow is super heavy you can use them in conjunction with tampons or menstrual cups to prevent any leakage.

The following photo shows just how thin period underwear is. It is literally only 1-2 mm thick. I am so impressed with how thin the gusset of period underwear is yet how effectively it works!

Do Period Undies Work?

Yes, as long as you match the absorbency of the period underwear to the flow of your period.

Period underwear comes in a range of different absorbencies ranging from light to moderate to heavy. The heavier absorbency period underwear does tend to be a bit thicker in the gusset but it is still less bulky than a pad.

I use moderate absorbency period underwear on my heavier period flow days, light absorbency period underwear on my lighter flow days and heavy absorbency for overnight. This works perfectly for me. I’ve never had an accident.

Period undies also work well if perspiration or light bladder leakage is an issue for you.

How Do Period Undies Work?

The exact design of period undies varies slightly between brands and products but generally period undies have at least three different gusset layers.

Next to your skin, the top layer, is a moisture wicking layer that is comfortable, breathable and wicks away moisture.

The next layer is super absorbent and it’s this layer that holds all the blood. In the heavier absorbency period underwear there may be two super absorbent layers.

The final layer is the leak resistant layer, which stops the blood from leaking through onto your clothes.

Benefits of Period Panties

Comfortable To Wear

Period underwear looks and feels like normal underwear. They are comfortable to wear.

There are many different styles of period underwear ranging from bikini to boyleg to full brief and even G-string, and more. There is a style to suit everybody’s preferences.

Easy To Use

Period underwear is easy to use. Just pull them on like you would with a pair of regular undies.

Tweens and teens find wearing period underwear much easier than fiddling with tampons especially when they first start menstruating.

Menstrual underwear is also so much easier for girls and women with various disabilities that make dealing with tampons and pads difficult.

Environmentally Friendly

Being reusable, period underwear is a lot more environmentally friendly compared to using disposable period products such as tampons and pads.

Over a lifetime from menarche, when periods begin during puberty, to menopause, the average woman will have approximately 450 periods and will use up to 15000 pads or tampons all of which go to landfill. Many pads and tampons are also wrapped in plastic which results in even more waste to landfill.

A simple switch to using period underwear can significantly reduce the single use waste associated with periods.

Cost Saving

Period underwear is reusable. Instead of having to pay for disposable tampons and pads each month you just pay the cost of period underwear once. Over time the cost of period underwear is significantly cheaper than the cost of tampons and pads. This is a valuable cost saving currently as the cost of living is skyrocketing in Australia and we’re all looking for where we can save some money each month.


Period underwear is convenient to use on days you are not sure if you will be getting your period or not, so you don’t get caught out.

What To Consider When Choosing The Best Period Underwear For You

What is the best period underwear for one person might not be the same as what is the best period underwear for another person. It is important to consider the following factors to determine the best period panties Australia wide for you.

Style Of Underwear

There are many different styles of underwear for periods Australia wide to choose from so there should be a style to suit your preference. There are bikini, full brief, boy leg and even G-String style period underwear styles. Choose the style that best suits your lifestyle, clothing choices and preference.

Initially when period underwear was first introduced about ten years ago it all seemed to be black in colour. Fortunately there is now more colour and print choices available.

Absorbency Level

The absorbency level of the period underwear you choose is an important factor to get right. Absorbency levels vary from super light absorbencies to heavy and maxi absorbency levels.

Putting it into more objective terms, period underwear absorption levels vary from 2.5ml to 50ml depending on the product you choose. Giving you a better understanding of what this means in practical terms, one regular tampon usually absorbs 5ml of blood.

To enable you to find the best period proof underwear for you and your period we have included available absorbency levels in our comparison table above.

Modibodi girls period underwear has fun prints as well as beautiful plain colour options. We both think these are the best period pants for tweens and teens.

My favourite is the sensual hi waist bikini with light to moderate absorbency and also this full brief with moderate to heavy absorbency.

Love Luna Period Pants Review – Best Cheap Period Underwear Australia

Love Luna Period Underwear
Love Luna Period Midi Brief Underwear

Love Luna is another great period panties Australia brand that offers a range of different absorbency levels and styles of undies, although not quite as comprehensive a range as Modibodi has. The range of colours is also quite limited although the tween/teen range has some other designs. Love Luna period underwear is sustainable, affordable and comfortable and they are Australian owned.

Love Luna period underwear briefs have 4 layers in the gusset including a soft cotton layer next to your skin, an absorbent layer to catch those spills, a waterproof layer to protect your clothes and sheets and prevent accidents and a sleek microfibre or cotton outer layer depending on the undies you choose.

In our opinion Love Luna are the best cheap period underwear Australia brand with their period undies starting at $15 each. Their sizing ranges from 6 to 24 but not all sizes are available in every style.

My daughter and I have found that Love Luna period underwear is true to size with the sizing being the same as other regular brands of underwear.

We both did not experience any leaking, discomfort, wet sensations or smell while using Love Luna period undies.

Scarlet Period

Scarlet Period is another good period underwear brand. It is Australian owned, uses eco-friendly packaging and their products are vegan.

Scarlet Period underwear has 4 layers. It has a super soft top layer that wicks away moisture to keep you comfortable and dry. Next is the absorbent layer that locks away fluid. A leak proof layer protects you from having accidents and the final layer is a breathable outer layer that maximises airflow to keep you fresh all day.

Out of all the period underwear brands reviewed Scarlet Period underwear has the smallest range of styles, absorbencies and sizes. See the above table for more detail.

When we tested Scarlet Period underwear we found this brand ran small to size. We recommend buying one size bigger than your usual underwear size to ensure a comfortable fit.

Bonds Period Undies Review

Bonds Bloody Comfy Period Undies is another brand of period underwear in Australia. They have a range of 4 different absorbencies ranging from ultra light to heavy and their size range goes from a size 6 up to a size 20. The different styles include bikini, boyleg, full brief and tanga.

I tried the full brief heavy absorbency Bonds undies overnight and these were my least favourite from the brands featured in this article. The gusset in these undies felt bulky to me, which admittedly matters less when you only wear the undies overnight, but I also didn’t think the gusset went up far enough in the front although they went up a long way at the back. I usually go to sleep on my side but wake up on my tummy. When I woke up in the morning I found I had come very close to leaking at the front in these undies. I have read several other Bonds Bloody Comfy reviews that share a similar finding. If you are not a tummy sleeper however the height of the gusset at the front probably won’t be an issue for you.

Frequently Asked Questions About Period Underwear

How Do You Wash Period Underwear?

Period underwear is machine washable in cold water but usually does need to be rinsed briefly beforehand to help remove the blood.

Avoid using fabric softeners on period underwear and avoid putting them in the tumble dryer. Ideally period underwear should be line dried outside. Understandably we did find period underwear takes longer to line dry than regular undies.

Read and follow the manufacturer’s washing guidelines on the tag of your period underwear to prolong the efficacy and lifespan of them.

How Long Does Period Underwear Last For?

Most brands advise that their period underwear will last for at least one year, and sometimes up to two years. It really depends on how often you wear them and how well you take care of them. This is pretty much the same length of time regular undies last for.

How Many Pairs Of Period Undies Will I Need

The answer to this will vary for each person depending on if you are pairing the undies with other period products or wearing them on their own, how heavy your flow is and whether you will be washing your period undies each night or washing them all together on weekends.

Personally I wear one pair during the day and then wear a fresh heavy absorbency pair at night. I do know that some women with very heavy flows change their period pants during the day as well as wear a fresh pair at night.

It is recommended that period underwear is line dried outside and not popped into your dryer. So you need to take this into consideration as well when working out how many pairs you will need. I suggest starting out with 6 pairs, 3 daytime absorbency pairs and 3 night time absorbency pairs and then see if you need more or not.

Do I Need To Change My Period Underwear Several Times A Day?

No, you don’t need to change your period underwear several times a day although I do change into a fresh pair of period undies at the end of the day when I go to bed. You do however need to make sure you buy the right absorbency level of period underwear to match your needs.

Absorbency levels vary from super light absorbencies to heavy and maxi absorbency levels. Maxi absorbency period underwear can hold up to 50mls.

You can check out the absorbency levels of our featured period underwear brands in the table above.
