Modibodi review: period proof & leakproof underwear + menstrual swimwear.

Any page on this website may contain affiliate links. Please see our disclaimer for more info.

One of the first blog posts I ever wrote was about more sustainable and healthy ways to have a period. There are many ways to do it, but my favourite has always been period proof underwear. They are much more environmentally-friendly than disposable pads or tampons, and much more comfortable than menstrual cups in my opinion.

I am also an advocate for period proof swimwear now that they are an option! I have given up using my cup completely since swimwear for menstruation became a thing. I never liked it much, and very pleased that there are more waste-free and healthy alternatives available now.

Here I’ll answer all of your questions about period panties and period swimwear, with this detailed review from my experiences with the brand Modibodi. I know there are many brands available now, but as I have only used Modibodi personally, they are all I can comment about. Thankfully for me, they are also awesome, so I haven’t had to shop around!

Modibodi sent me some of their period-proof swimwear in return for my honest review. Below are all my own thoughts and my own words: I do not publish pre-written text or other people’s ideas, or seek approval from anyone before publishing.

Leakproof period underwear review

So I have been using menstrual cycle underwear from Modibodi for several years now, both at home and while travelling overseas, and I’ve never been more confident having my period. They’re really easy to travel with, simple to care for, and I find them much more comfortable and easy to use than menstrual cups.

How do period panties work? 

I believe all brands have the same idea, which is combining a reusable pad with knickers/panties to make them leak proof underwear. However, from my experience with several brands of washable menstrual pads, period briefs are really, definitely, so much more comfortable!

Modibodi have several different absorbencies, and they all have a moisture-wicking top layer, an absorbent middle layer, and a waterproof bottom layer which provides the leak-proof protection.

In two and half years of using Modibodi for every one of my menstrual cycles, I have never had a leak, so I can verify that they do their job well.

Can they be used for other reasons?

Yes, Modibodi’s period knickers are useful for light bladder leaks, discharge, and as a back-up for other menstrual items like cups or tampons. Modibodi is an approved supplier in most Australian states for the NDIS, too.

If you need the underwear for leakage from other products, Modibodi are a safe and comfortable option. Some women who have very heavy flows like to use them this way and feel protected and safe from leaks.

What do they feel like?

Most of the absorbencies feel exactly the same as regular underwear. The heavy flow ones feel a bit more padded, but not as noticeably as reusable or even disposable pads. They are also soft and smooth, unlike disposable pads. And they are more comfortable than they used to be, with flatter seams now too.

My old Modibodi heavy absorbency.

One of my first pairs of heavy absorbency Modibodi underwear. The absorbent layer is attached at the front and back but not the sides, and they are comfortable to wear but the newer version is better. (they are still in great condition after more than 30 periods though!)

My newer pair of heavy absorbency Modibodi.

My more recent pair of Modibodi heavy absorbency underwear. The sides are fully stitched now, and they’re even more comfortable.

Some women—including me!—felt a bit strange to free-bleed into underwear the first few times. Especially if you’re used to tampons or menstrual cups, it definitely feels different. Now, I like the freedom of not having to be plugged up. To me, it feels more natural, but I understand that others find that cups or tampons feel safer.

Do you need to change reusable menstrual underwear throughout the day?

Not like a pad, no. On my heavy days I use the most absorbent period undies, and they last me all day or overnight. I do like to have a quick shower before changing into another pair after waking or after a whole day of heavy flow.

Modibodi’s heaviest absorbency holds 15-20ml of fluid, which is equivalent to two tampons or three teaspoons. It doesn’t sound like much, but it has always been enough for me for a whole day or whole night throughout my heavy days. I have never changed mine in the middle of the day, or even wished I could.

Picture of three teaspoons.

Three teaspoons of blood is an average heavy flow.

However, if you have a very heavy flow and you’re exclusively using the underwear (not as a back-up for another product) you might feel more comfortable changing them once throughout the day.

You can definitely use Modibodi’s underwear for heavy periods, just be prepared the first few times until you know for sure that they are absorbent enough for your needs. I’d recommend taking an extra pair with you for the day if you are worried.

Then if you want to change them while you’re out of the house, you will need a waterproof wet/dry bag to contain your first pair. This is the same process as changing a reusable pad throughout the day: just keep it contained until you can deal with it at home.

Do they get sticky on the top like a pad does?

Thankfully, no! The top layer wicks away fluids and keeps you feeling dry. If a particular area gets quite full after wearing them all day, you might start to notice a bit of fluid on the top, but they still don’t feel gross at that point like many pads do.

Do they smell? Even after wearing them all day?

No! The moisture-wicking layer fights bacteria with a non-toxic antimicrobial. I was concerned about that too, especially as pads do smell after awhile. But I’m happy to report that they really are sanitary underwear!

After a whole day of wearing Modibodi during a heavy flow, you will notice some blood when you take them off. But they do a great job of containing all odours, as well as containing fluids and perspiration.

Is period underwear very messy?

Not really, no. They do not leak or get blood throughout your washing (I’ll explain how to care for them next). But you do have to rinse them by hand and touch some blood, as with all reusable menstrual products. Only with disposables are you able to not touch blood at all, but of course they have many other drawbacks for the environment and your health.

Menstruating is a natural bodily function, and it’s not disgusting or wrong to wash away your blood. Some people like to be able to see how much blood they are releasing, and I do understand more about my cycle since using the underwear. But if you have haemophobia or a very high fear of touching blood, perhaps they’re not for you.

Do absorbent panties get stained?

None of mine have, after constant use for two and a half years. All absorbencies except for the moisture-wicking ones have a black top-layer, regardless of the underwear colour. None of them have faded or and there are no stains on mine, even the heavy ones.

The inserts of some of my Modibodi collection. Yes, it feels a bit strange to be showing you inside the underwear I have been wearing for years! But at least you can see they’re not stained.

How do you wash reusable period underwear?

It’s quite easy, you rinse them with cold water after use, and then wash them just like any underwear. Modibodi recommends washing in cold water, in a delicates bag. Never use fabric softener with them, and hang them on the line to dry whenever possible.

I usually rinse mine in the shower as it’s warming up, then throw them in the wash. As all of the styles contain some polyester, I wash mine in this Microfibre Laundry Bag.

Do Modibodi period briefs shed microfibers?

Yes they do, as do all textiles that contain synthetic fibres. I recommend using a Microfibre Laundry Bag for washing them, to avoid microfibers entering waterways. And I still believe that they are better for the environment than disposable pads and tampons.

What fabric are Modibodi’s period underpants made from? Are they vegan?

There are several materials used, and a vegan range is available. Modibodi’s swimwear and active leggings are vegan, in addition to a range of bikini underwear.

  • Vegan:
    Outer – Bamboo/Spandex, Liner – Polyester Spandex & Polyester, Trim – Polyester & Nylon
  • Classic and Sensual:
    Outer – Bamboo & Spandex, Liner –  Merino, Spandex & Polyester (only Merino in Moisture-Wicking style), Trim – Polyester & Nylon
  • Seamfree:
    Outer – Polyamide Elastane, Liner – Merino, Spandex & Polyester (only Merino in Moisture-wicking style), Trim – Polyurethane
  • Contour:
    Outer – Polyester Spandex/Polyester, Liner – Merino, Spandex & Polyester, Trim – Polyester & Nylon
  • Maternity briefs:
    Outer – Bamboo & Spandex, Liner – Merino, Spandex & Polyester, Trim – Bamboo & Spandex
  • Activewear briefs:
    Outer – Merino Wool, Liner – Merino, Spandex & Polyester (Marino only in Moisture-wicking style), Trim – Polyester & Nylon

How do you travel with period absorbing underwear?

I found it simpler than travelling with my menstrual cup. All I did was rinse the underwear after using them, and the kept the rinsed pairs in my wet bag until I had the chance to do laundry. They dry fairly quickly and aren’t as obvious as reusable pads on the clothesline too!

The lighter-flow options are fantastic for days when you think you might start your cycle, or if it seems finished but you’re not quite sure. And there are also moisture-wicking only styles too, which are handy for travel to very hot and humid places if you worry about perspiration and odours.

During travel, I was especially glad to have leakproof panties. Sometimes a travel journey takes a lot longer than expected, and I always seemed to be in transit during my cycle.

I have worn them in a remote village in Northern Thailand for trekking to see elephants in the forest, and I’ve used them while volunteering to help sea turtles on Tioman Island too. I’ve worn them on road trips in Australia and tuk-tuks in Siem Reap, as well as buses, planes, and trains!

With Modibodi I always felt comfortable anywhere we were, and knew I was safe from leaks or an early-arriving period. This is on one of those journeys!

Us females have to be extra organised when travelling. More often than not, on days we have moved from city to city or country to country, I have gotten my period. Even the first day we left Australia, yep, I got THAT day. Such fun! . I thought of writing this post after we caught the bus to Battambang the other day, as it of course happened again. I'm sure most of you can appreciate that although this is a part of life for all women, it makes some days more uncomfortable and adds an extra layer of stress on top of travelling. . So I am very happy to have found an eco-friendly solution that enables me to be comfortable all day, and not have to worry about mishaps or leaks as we travel! I solely use period-proof underwear by Australian company Modibodi. They are so much more comfortable than wearing pads, and although I have a menstrual cup, I do not find it as easy to use or as stress-free. . With the underwear I don't have to worry about anything on-the-go, whether expecting my period or in the midst of it. I have not had a single leak in almost 12 months of using them (unlike every other product I've tried). So I am confident to say they really are leak-proof! . If you're interested in trying them too, this is my affiliate link to their website: https://t.cfjump.com/45797/t/43611 . Some are on clearance at the moment, and they have some starter packs and a 30-day risk-free trial for new customers. Feel free to ask me any questions, here or DM! . I also have a blog post about 5 eco-friendly period solutions, and why it’s so important to go green: https://smallfootprintsbigadventures.com/sustainableliving/periods/ . . . . . #smallfootprintsbigadventures #ecofriendlyliving #sustainableliving #periods #traveldays #periodpower #womenstrong #periodproof #periodproofunderwear #beconfidenteveryday #beconfidentnomatterwhat #cleanliving #ecoblogger #girlpower💪 #travelmom #travelingmom #travelmum #womenempowerment #stressreducer #ladiesgoneglobal #femaletravelblogger #lifeofawoman #nothingsgonnastopme #gogreen💚 #environmentallyfriendly #greenliving #partofthesolution #thinkeco #wanderlightly #reusables

Do they make plus size period panties? 

Yes, Modibodi’s range goes up to 6XL or size 26. They also have suggestions for curvy physiques on their website.

Is their sizing accurate?

I have found all pairs I have tried to fit true-to-size, and I have bought several different styles now: sensual high-waist, boy-leg, and classic bikini.

A pair of my sensual high-waist Modibodi (that are 2 and a half years old).

A pair of my sensual high-waist Modibodi (that have been in use for over two and a half years, and still going strong!)

I haven’t bought the contour or seam-free ranges personally though, and notice on their website it says the seam-free ones feel tight at first in your standard size, because they will stretch considerably. But I would be surprised if some styles didn’t fit true-to-size while others did.

Do they make underwear for your period for teens and tweens?

Yes, there is a range of period panties for girls now too. Adult underwear sizes go down to size 2 or 4XS, which is the equivalent of girl’s size 8-10. And Modibodi also has underwear specifically for youth called Red, which has some bright and funky boyshorts and bikini styles in girls sizes 8-16 or XS to L.

Can I return my Modibodi underwear if I’m not happy with them?

Modibodi offers a 30-day trial for first-time customers, on one item only. That means you can wear a pair of menstrual underwear during one of your cycles, and if you aren’t happy with it, you can return it for a refund (minus shipping costs). Modibodi asks you to complete a short survey to explain what you aren’t happy with.

You can also request a refund, credit or exchange on fully-priced, unworn items. They must have the hygiene sticker intact and be in their original packaging. Bundle packs are not included as they are already discounted. See more info on their webpage.

How long will my period proof panties last? Are they cost-effective?

I have been wearing mine for more than two and a half years, and most are still in great condition. Modibodi says they will last up to two years with good care, but in my experience, they will last even longer.

A couple of my pairs are starting to show signs of wear, but I am very impressed with how long they’re lasting. My original heavy underwear is still in excellent condition, as I only wear them during my cycle.

Another pair of my Modibodi that I have had for two and a half years. They are a bit stretchier now but still very comfortable and will get more wear.

They are certainly cost-effective when you compare several years of wear with two boxes of tampons or pads for every period. Like all reusable products, they cost more initially, but over the long run, they are far cheaper than their disposable counterparts.

What countries is Modibodi available in?

Modibodi is an Australian brand that is available internationally. Their Australian depo ships to the Americas, Oceania and Asia, and their UK store ships throughout Europe. As shipping comes at a cost, I suggest purchasing with other girls or women in your life to reduce the financial and environmental burden.

  • Period underwear Australia and NZ:
    Free shipping for orders over AU$120.
  • Period underwear other Oceania:
    Modibodi ships to the Cook Islands, Fiji, Solomon Islands, Samoa, Tahiti and Vanuatu.
  • Period underwear Asia:

  • Period underwear Canada and the Americas:
    Free shipping to the US for orders over US$75. Unfortunately Modibodi no longer ships to Canada, but does ship to Mexico.
  • Period underwear UK and Europe:
    Modibodi ships to Austria, Belgium, Cyprus, Denmark, England, Estonia, Finland, France, Germany, Greece, Italy, Ireland, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Portugal, Poland, Scotland, Slovakia, Slovenia, Spain, Sweden, Switzerland and Wales.

Is Modibodi socially responsible?

I believe so. They are made in China by a supplier who adheres to OEKO-TEX® fair work standards, and Modibodi supports various charities and movements to empower girls and women including the Sustainable Period Project, Days For Girls and ChooseREAL.

Modibodi also has their own Give a Pair program, which helps customers donate menstrual underwear to women in need across Australia.

Where to buy Modibodi underwear? 

Modibodi is available online and in a few selected stores.

Leakproof period swimwear review

I have started using Modibodi’s menstrual swimwear this year, and it’s still amazing to me that bathing suits can be period-proof! Modibodi’s menstrual underwear is definitely not for swimming in, but their new swim technology is.

I tested them while on my cycle in the bath first, so I could move about in private and really see what was happening. I have also worn them in public and had no issues at all, so am confident in reviewing them for you. I’ll try to answer all of your questions about period swimwear now.

Chilling in the first bikini I’ve worn for a very long time!

Can you go swimming on your period without a tampon?

Yes, you can use a menstrual cup or sea sponge, and now you can use period-proof swimwear too.

Modibodi’s swimwear is not designed to be used alone on heavy period days, but can be used on light days, and as a back-up to other menstrual options.

How does a period proof bathing suit work?

Modibodi’s swimwear uses their own Modifier Swim Technology, for which the details are a trade secret. I can tell you that gusset has a top layer which stops odours and fights bacteria, and the bottom layer is extra waterproof protection via water-repellent fabric.

Can they be used for other reasons?

Yes, Modibodi’s swim range is also suitable for discharge, light bladder leaks and spotting.

What do they feel like? Is it like wearing a menstrual pad for swimming?

No, not at all. The swimwear feels and looks just like normal bathers. There is no bulkiness or padding (except in the cups if you want padding there).

I find my Modibodi bikini to be very comfortable, and it fits well with no need to continually adjust it. I personally dislike halter-neck tops so was glad to see that both the bikini and one-piece bathing suit had proper straps.

And I haven’t worn bikini-style bathing bottoms for many years, as I really hate them riding up my bum! But these have good butt-coverage and don’t move around as I swim. They are not high-cut around legs either, but the bikini is quite low around the tummy.

My bikini is very comfortable to wear, and never exposes any areas by surprise!

Do you need to change leak proof swimwear while at the beach or the pool?

No. Modibodi’s swimwear is equivalent to 1 & ½ tampons, or 10ml/2 teaspoons of fluid. That is why they are only for light period days, so for heavier days it is recommended to use another product as well.

I actually tested mine in the bath on a heavy flow day and had no leaks, and I see some other women also say their absorbency is greater than what is stated. But Modibodi makes no guarantees for flows above ‘light’.

Do period panties for swimming smell?

Modibodi’s do not smell at all, due to the top layer which fights bacteria and odours. I’m not sure how exactly, but there was no smell coming from mine after they had been used.

I even – ahem – tested several functions while in the bath for you, and am happy to report that no odours were detectable! (the things I do for you guys!!)

Are swimwear for periods messy?

Just like menstrual underwear, they contain bodily fluids until you are ready to wash them. There are no leaks or mess, but you have to rinse them in cold water after use.

Do period bathing suits get stained?

Nope, Modibodi’s are stain-resistant as well as odour-resistant. Both styles are black with black gussets.

How do you wash reusable period swimwear?

After use, rinse them with cold water, and then add to the cold wash cycle in a delicates bag, or wash by hand with mild detergent and line dry. Never use fabric softener with them.

As all of the styles contain some polyester, I wash mine in a Microfibre Laundry Bag.

Do Modibodi’s period bathers shed microfibers?

Yes, like all swimwear made from synthetic fibre does. I wash mine in a Microfibre Laundry Bag.

What fabric are Modibodi’s period swimmers made from? Are they vegan?

Yes, they are vegan! They are comprised of:
Outer — Polyamide Lycra, Lining — Polyester, Trims — Polyester & Nylon.

Do Modibodi’s waterproof swimwear for periods have sun protection? 

Yes, both the bikini and the one-piece swimsuit are rated UPF50+. You’ll still need a to cover up with a hat, rashie and/or quality sunscreen for full protection though! We choose reef-friendly, palm oil-free sunscreen that is made from natural ingredients.

Picture of Emma wearing Modibodi bikini at the beach.

It’s a good feeling to know I’m safe from leaks while at the beach!

Do they make plus size period swimmers? 

Yep, both styles from Modibodi’s swim collection go up to 2XL or size 18, and cup size DD.

Do they make menstrual bathers for teens and tweens?

Yes, Modibodi’s swim collection starts at girls size 12-14, equivalent to ladies size 2XS/6.

Is their sizing accurate?

My bikini is accurate and fits well. Happily I have not experienced any riding up from my period swim bottoms! And my bikini top is comfortable and includes removable padding in the cups.

My swimwear bottoms cover my butt well and do not ride up while moving around.

Can I just buy period bathing suit bottoms?

Yes, you can! Modibodi has the bikini bottoms for sale separately now. They are great to match with your rashie or favourite swimming top, or even for wearing underneath other swimwear if you like.

Can I return my period swimsuit if I’m not happy with it?

Yes, if you are a new customer to Modibodi, the swimwear does qualify for the 30-day refund. So if you use them for one menstrual cycle and you’re not happy with their performance, you can get a full refund (minus the shipping cost).

Where to buy Modibodi swimwear?

Modibodi is available online and in a few selected stores.

Final thoughts

I hope that’s answered all of your questions about menstrual underwear and swimwear! I am really happy with mine and glad there are such great options available for waste-free periods now.

If you have any further queries you can ask in the comment section below, or send me an email and I’d be happy to help.

(Please don’t comment about my body though, negatively or positively. This is about the swimwear and panties, not how I look. They are suitable for all shapes and sizes, and I am trying to accept my body as it is and be ok with wearing so little in a very public way.

Less talk about appearance and more talk about new technology and sustainable solutions is what we all need!)

  1. I can’t believe someone did not come up with period proof underwear sooner and I sincerely hope they will become an environmental game changer for women. I am pleased they can also be used for light bladder weakness 😉
    A brilliant post to add to #GoingGreen – offto share it widely now! Thank you.

      Thanks Rosie! I think they will be a game changer, as they’re just so easy and comfy. I figure why wash pads AND underwear if you can just deal with one (more comfortable) product?

    Hi Emma,
    This is great. It is about time someone came up with period underwear. You did a good review on them and very thorough with your information. Thanks for such a good article. Congratulations on being featured on Going Green LInky.

    • Emma says:

      Thanks Marla! Yes, it is amazing that they hadn’t been invented earlier!! We’re lucky to have them and other zero-waste options now.
