What Is Period Underwear?
Period underwear is exactly as it sounds – it’s a type of undergarment specifically designed to be worn during menstruation in place of or in combination with tampons and pads.
How Does Period Underwear Work?
One of the most common questions about period-proof underwear is: How does it work?
Well, there’s not much to it, really. Wearing period underwear is a lot like wearing a pad – except that the pad is built in. Although this seems like a small difference, it has a huge impact on how convenient and comfortable period undies are.
To trap in menstrual blood, period underwear features several layers of absorbent material in the crotch area.
What’s particularly impressive about period undies is that they can hold a substantial amount of blood – equivalent to as much as two tampons’ worth!
This, of course, also depends on the kind of period underwear you choose as there are several options available. You can choose period undies for light-, moderate- and heavy-flow days.
The extra padded layer that holds the menstrual flow consists of fabrics designed to absorb, pull away and trap the liquid. The following indicates the usual materials used in the different layers; however, material combinations may vary depending on the brand and absorbency level.
- Water-resistant outer layers: Nylon and Lycra, polyamide and elastane or cotton and spandex, bamboo, TENCEL™
- Wicking layers: Microfiber polyester, polyurethane laminate (PUL), spandex, modal
- Absorbent layers: Carbon with polyester, acrylate, polyester, cotton
Aside from the above, many products also contain antimicrobial components that ensure excellent odour control.
Know Your Flow – How Heavy or Light Is Your Period?
Similar to traditional products, period underwear is classified based on the level of heaviness of the menstrual flow. So if you’re shopping for period undies, you can choose from these commonly used categories:
- Ultra-light: Can hold fluid equivalent to 1 light tampon or panty liner
- Light: Can hold fluid equivalent to 1 regular tampon or 2 teaspoons
- Moderate: Can hold fluid equivalent to 3 regular tampons or 6 teaspoons
- Heavy: Can hold fluid equivalent to 4 regular tampons or 8 teaspoons
- Super heavy: Can hold fluid equivalent to 5 regular tampons or 10 teaspoons
While the above system of classification is commonly used, some brands simply state how many tampons’ worth of fluid their product can hold.
Where to Buy Period Underwear
Not sure where to buy period underwear?
If price is a priority, there are plenty of cheap options available at big retailers like Kmart, Big W, Coles and the like. However, if you’re after good-quality period underwear, you can always go online where you can also take the time to choose the style, cut or colour you want.

How Long Can You Wear Period Underwear For?
The length of time you wear period undergarments will depend a lot on how heavy your menstrual flow is and what day you’re on within your period.
Most manufacturers say it’s safe to keep period underwear on for 8-12 hours. However, it’s best to change your period panties when you are no longer comfortable. So, always be on the ready and bring extras, especially if you’re away from home.
Also, you can use period underwear in combination with other menstrual products like tampons, pads and menstrual cups. This way, you won’t need to change your period undies as often during heavy flow days.
Reusable Period Underwear vs Disposable Period Underwear
Reusable period underwear is the antithesis of disposable period underwear.
The former is the ideal period care alternative to the latter as reusable period underwear eliminates the waste produced when people use disposable period underwear that cannot be recycled and is usually non-biodegradable.
How to Wash Period Underwear
To remove stains from period underwear:
- Rinse them under cold running water immediately after wearing them. Keep rinsing until the water runs clear.
- Place the period undies in the machine together with your regular wash on the cold cycle.
- Once done, hang them up to dry.
If you’re pressed for time and cannot wash your heavily-soaked period underwear right away, soak it in cold water with some soap. Don’t over-soak your undies as the soak water could become stale.
Can You Swim in Period Underwear?
The short answer here is a resounding ‘yes’!
There’s waterproof underwear for swimming when you have your period, and there are several brands that provide period underwear you can use with your swimwear.
Pros and Cons of Period Underwear
While period-friendly women’s underwear may sound like a trendy product; it most certainly is. In fact, it’s probably here to stay as it provides the following pros and benefits:
- It doesn’t need to be changed or replaced frequently.
- It is discreet – no one needs to know you’re on your period, and your underwear won’t tell.
- It is highly absorbent and can be worn for hours.
- It is flexible, thereby freeing the wearer from having to worry about misalignment and leaks.
- It is cost effective as it can be worn over and over again for a long time.
- It is eco-friendly as it doesn’t generate waste; it just needs to be washed and cleaned.
- It is highly washable and quick drying.
- It is comfortable, breathable and moisture wicking.
- It is available in a range of styles, cuts, prints and colours.
- It’s perfect for concealing the dreaded camel toe.
However, it’s not all unicorns and roses with period underwear because of the following cons:
- Washing and cleaning period underwear tends to be messy because of the blood.
- It could prove inconvenient if you need to change your period underwear while you’re out in public or away from home.
- Period underwear may cost you some initially, as you may need to buy several pieces to ensure you’re covered for the entirety of your period. Then again, you won’t need to buy tampons and pads if you don’t want to – which also means huge savings in the long term!
In the battle between the pros and cons of period underwear, the pros are the clear winners.
How to Make Your Own Period Underwear
Handmade period underwear is easy enough to make as long as you have the right materials. But first, ask someone to take measurements of your waist, hips, crotch and legs, and record the information on a piece of paper.
Next, get the materials together, particularly for the three main elements for the gusset comprising the following layers:
- Top layer: The part that’s in contact with the skin, so choose breathable and soft cotton jersey material.
- Inner layer: The absorbent layer may include natural fibres like quilted bamboo jersey or wadding. You can also opt for Zorb which is a specialist fabric that can absorb impressive amounts of liquid really fast!
- Outer layer: This should ideally be waterproof as it will sit outside and against your clothes. You have several options available although most include a polyurethane cover.
Once you assemble the fabrics, it’s time to make the pattern. Pattern-making refers to the following activities:
- Marking the stitch lines
- Taping the pattern
- Drafting a custom gusset piece
When the pattern is ready, you can start cutting the fabrics and then sew away!

Can You Use Incontinence Underwear for Periods?
Yes, you can, since both involve fluids. However, you may need to change your period underwear more frequently for incontinence as urine is watery, unlike blood which usually has a thicker consistency.
