Frida Mom Disposable Boyshort Underwear
The Frida Mom Disposable Boyshort Underwear are soft, stretchy postpartum underwear designed for the days after birth when comfort matters and doing extra laundry definitely doesn’t.
Made from breathable microfiber and spandex, these disposable postpartum boyshorts provide full coverage while securely holding maternity pads, cooling liners and instant ice pads in place. They’re seamless, tagless, mesh-free and completely opaque, giving new mums a much more comfortable alternative to traditional hospital-style mesh underwear.
Wear them during postpartum recovery, change them when needed and simply dispose of them. Your good underwear can stay safely in the drawer until you’re ready for it again.
A Better Alternative to Hospital Mesh Underwear
Disposable underwear makes a lot of sense after having a baby. Unfortunately, the traditional mesh underwear often associated with maternity wards isn’t exactly known for comfort.
Frida Mom takes a different approach.
The Boyshort Underwear is made from soft microfiber and spandex rather than scratchy fishnet-style mesh. The fabric is breathable, stretchy and opaque, so it feels much more like wearing normal underwear while still giving you the convenience of something you can dispose of after use.
There’s no need to worry about staining your favourite underwear during the early days of postpartum bleeding, and there’s one less thing to wash when you get home with your new baby.
Designed to Hold Your Postpartum Recovery Layers in Place
Postpartum underwear has another important job beyond simply being comfortable. It needs to keep everything else where it’s supposed to be.
The Frida Mom Boyshort Underwear is designed to securely hold your maternity pad and other postpartum recovery products against the body.
That makes them particularly useful with products such as Frida Mom Instant Ice Maxi Pads and Perineal Cooling Pad Liners.
The four-way stretch allows the underwear to move with you while helping prevent your recovery layers from shifting around every time you stand up, sit down or walk.
Full-Coverage Boyshort Design
The boyshort cut provides generous rear coverage with comfortable openings around the legs.
Unlike the Frida Mom Disposable High Waist Underwear, the Boyshort version has a lower-rise design that sits closer to the natural waist.
This makes the Boyshort a great choice for mums who prefer the feel and coverage of traditional boyleg underwear without wanting a particularly high waistband.
For c-section recovery: The Frida Mom Disposable High Waist Underwear may be the better option because its taller waistband is designed to sit higher on the abdomen. The position of a Boyshort waistband will vary depending on your body shape, so you should avoid any waistband that rubs or places pressure on your incision and follow the advice of your healthcare professional.
Soft, Seamless and Tagless
The last thing you want during postpartum recovery is an irritating seam or clothing tag rubbing against sensitive skin.
Frida Mom Boyshort Underwear is seamless and tagless, with soft stretch fabric designed to accommodate your changing postpartum body without unnecessary digging or restriction.
The microfiber and spandex construction provides four-way stretch, allowing the underwear to expand in every direction rather than feeling tight as your body gradually changes during recovery.
Mesh-Free and Completely Opaque
These aren’t see-through hospital fishnets.
The mesh-free microfiber fabric provides proper coverage while remaining breathable and stretchy. That makes them feel considerably more like normal underwear while retaining the convenience of a disposable product.
They’re also latex-free, making them suitable for mums wanting to avoid latex in their postpartum underwear.
One Size Medium/Large
The Frida Mom Disposable Boyshort Underwear comes in one stretchy Medium/Large size.
The waistband stretches from approximately 71cm to 107cm (28 to 42 inches).
Because your body immediately after birth may be different from your usual clothing measurements, we recommend using your actual waist measurement rather than relying only on your normal Australian dress size.

How to Measure for the Best Fit
Measure around your waist where the Boyshort waistband will actually sit.
Keep in mind that your postpartum body may be larger than your usual waist measurement during the early weeks after birth. You’ll also typically be wearing these underwear with a thick maternity pad, cooling liner or Instant Ice Maxi Pad.
Allowing a little extra room when comparing your measurement with the size chart can therefore provide a more realistic indication of fit.
Australian dress sizes should only be treated as a guide. Your actual measurement is more useful when deciding whether the Medium/Large size will suit you.
Ideal for Vaginal Birth Recovery
Following a vaginal birth, the full-coverage boyshort design helps hold postpartum pads and cooling products securely against the body.
The soft four-way stretch fabric accommodates a changing postpartum body without the scratchiness of traditional mesh underwear.
If you have stitches, tearing or an episiotomy, follow your midwife or healthcare professional’s individual instructions regarding postpartum care and clothing.
What About C-Section Recovery?
The Boyshort version may be suitable following a c-section depending on where the waistband sits on your individual body.
However, Frida Mom also makes Disposable High Waist Underwear, which is the version we would choose when keeping the waistband higher and away from the incision is important.
Following a caesarean birth, avoid clothing that rubs against or places pressure on your incision and always follow your obstetrician or healthcare professional’s recovery advice.
Perfect for Your Hospital Bag
Disposable postpartum underwear is worth organising before your due date rather than discovering you want it once you’re already in hospital.
Each pack contains 8 pairs, so you can pack several in your hospital bag and have the remaining pairs waiting at home.
If you expect to use disposable underwear for more than the first few days, consider having an additional pack ready. How many pairs you’ll actually use depends on your individual recovery and how frequently you need to change.
How to Use Frida Mom Disposable Boyshort Underwear
- Prepare your pad first. Place your maternity pad, cooling liner or Instant Ice Maxi Pad securely inside the underwear.
- Pull the underwear on gently. Allow the stretch fabric to settle naturally against your body without forcing or overstretching it.
- Check your recovery products. Make sure your pad and any cooling layers are positioned comfortably and securely.
- Check the waistband. Ensure the waistband isn’t rubbing against any tender or healing areas.
- Change when required. Replace the underwear as needed during postpartum recovery.
- Dispose after use. Place used underwear in the bin. They are designed for disposable convenience, so there’s no washing required.
