Modibodi period underwear – your postpartum bleeding solution covered
*This post is sponsored by Modibodi period underwear
We women can’t catch a break, can we? First, we have monster periods that seem to last forever until we get pregnant and our periods stop for a while. Great, a break from periods! But, then here comes a side of morning sickness, constipation and a growing belly, which plays havoc on your pelvic floor.
Oh, but that’s not it! You need to have the baby first, so let’s bring in some labour pains (ouch!) and then birth itself. Phew, it’s finally over. Nope, sorry! Allow me to introduce your postpartum period, the mother of all periods, which actually isn’t a period at all. It’s called lochia which is a vaginal discharge that contains blood, mucus and uterine tissue.
Lochia can last between four to eight weeks too, whether you’ve had a vaginal birth or an abdominal birth. If you’re breastfeeding, your periods might not return for up to a year, although that’s slightly different for formula feeding mums where your period may return sooner.
These postpartum periods are not the same as regular pre-pregnancy periods. They’re ramped up and on speed, like someone has opened a gate and forgot to close the door. Goodbye thin tampons/pads and hello heavy bleeding, leaking, and the period cup! But these types of period-controlling paraphernalia still come with a leakage caveat, especially if your periods are ridiculously heavy like mine.
Thankfully, we live in an age where solutions are constantly popping up out of the woodwork to tackle these very common problems.
One of those solutions is period underwear, designed to step away from the chemically invasive tampons and the irritating aeroplane-like pads that are so big and so uncomfortable. In this article, we’ll talk more about what period underwear actually is and Modibodi‘s* range of leak-proof apparel for women with periods and leaks.
But, what exactly is period underwear?
So what is period underwear and why is it leading the fight against heavy periods and leakage? The period pant feels like regular underwear but is an absorbent underpant that protects you during your cycle and soaks up menstrual blood, while keeping moisture away from your skin.
What is period underwear made of?
Period underwear looks like normal underwear but the gusset has a moisture wicking layer that sits against the skin designed to wick away moisture and control odour to keep you fresh and dry, a microfibre middle layer that absorbs fluid and locks it away and finally a bottom layer which is a leak-proof barrier for secure protection.
Why should I use period underwear? What are the benefits of period underwear?
Unlike disposable pads, you can use period underwear more than once and they can even last from 6 months to 2 years, so they should last you a long time if you look after them. However, there isn’t really a ‘right’ period product from which to choose. Whatever you decide will be right for you, based on your personal comfort and well-being. Some people choose to wear period pants with another disposable product like tampons, or with the menstrual cup, which is what I do.
Do period undies feel wet?
The material used to create period pants are designed to stop moisture leaking onto your skin so they shouldn’t feel wet, if they do this means you have breached the absorbency levels of the product and will need to change them, just like you would any other period product. Switching them out regularly will help you feel fresh.
How do you wash period underwear?
Washing instructions will differ based on the brand, so read the instructions before you wash your period underwear, to avoid damage. It is advisable to wash them in the delicate cycle with no bleach to protect your underwear and keep them long-lasting.
How many pairs do I need for my whole period?
This depends on how often you do your laundry and how heavy you are. Some users can use one pair a day, and one at night. So you may need around three to five pairs of period underwear (for heavy periods), depending on your period length and the frequency with which you do your laundry.
How to shop for period underwear
There are a few brands who specialise in period underwear. We will focus on Modibodi‘s* period underwear and how they can help women feel more comfortable and in control during their periods.
What is Modibodi underwear?
Modibodi* is the UK’s number 1 period and leak-proof underwear brand. They also have a range of products including TEEN (teenagers) mens, maternity and activewear.
They’ve become known for their high quality, sustainable underwear that is breathable, stain-proof and leak proof. Modibodi also aims to highlight the negative effects that disposable sanitary products can have on the environment and to reduce the shame/stigma around periods.
How do Modibodi underwear work?
The absorbent panel in the period underwear is actually only 3mm thick, but it comprises three layers of their Modifier Technology™ which can hold up to 20mls of flow. That’s around two to four tampons!
The top layer wicks away the moisture and fights bacteria. It also stops smells so you stay dry and fresh.
The middle layer absorbs the fluid and locks it away (around 2.5 to 20mls depending on the flow you choose)
The bottom layer has extra waterproof protection, so you’re kept safe and secure from any leak-throughs.
Do you need to wear a pad with Modibodi?
Modibodi* underwear essentially has the pad woven in, so you don’t need a pad on top.
How often should you change your Modibodi? How to use Modibodi period underwear
Modibodi recommends you go with the absorbency level that matches your flow. If you need to change underwear throughout the day, then Modibodi offers a wet/dry bag where you can store your undies until you get home.

How long does a pair of Modibodi last?
Modibodi period panties last over a 100 washes, depending on how well you look after them and you follow the instructions on how to keep them clean and dry.
How to wash Modibodi period underwear?
Modibodi period pants are machine washable, it’s best to rinse them first with cold water and then to wash on a gentle cold machine wash and hang to dry. Use a laundry bag to wash your Modibodi garments, so they don’t get snagged on things like zips. Don’t use fabric softeners or strong detergents like stain removers as they break down the hi-tech function and reduces the durability of the fabrics and trims.
Once dry, store your Modibodi period undies in a dry laundry bag for extra protection.

FAQ
Why do my Modibodi undies smell?
Other questions asked were:
- Do period undies smell?
If your period underwear has been left soaking for more than a few hours or stored when they’re not yet dry, then they can end up smelling musty. It’s important that you wash them and hang them out to dry completely after use.
How will I know when to change my period underwear?
Most period underwear brands suggest changing your period underwear when you feel ‘wetness’ because that means your pants can’t absorb anymore. As your period progresses, the absorbency changes, so make sure you’re wearing the appropriate pants for your flow.
Can you wear 2 pairs of underwear on your period? Does it help with anything?
You shouldn’t need to wear 2 pairs of undies when wearing period underwear. Instead, it would be best to try increasing the absorbency of the style you are wearing, for example moving from mod-heavy absorbency to maxi.
How do I stop bleeding through my pad, underwear and pants when on my period?
Other questions asked were:
- How do I stop leaking through my pad during my period?
Make sure you’re wearing the right full brief period proof underwear with the right absorbency and you’re changing regularly during a heavy flow. Just like you would with other period products, as soon as you feel any dampness on your skin make sure to change your period underwear, as this means you have breached the products absorbency level.
