Invizi Women's Washable Bikini Brief

Use, Wash, Repeat

Built-in Absorbency

Bamboo Blend

Soft & Gentle

  • Up to 100mL maximum absorbency
  • Built-in absorbency — four discreet layers for protection you can trust
  • Quick-dry lining — wicks away wetness to keep you feeling dry
  • Real underwear feel — exactly like regular undies, just with added protection
  • Wear, wash, repeat — machine washable for your convenience

Don’t let the pretty lace fool you — these bikini briefs mean business. With built-in absorbency for light leaks, they keep you dry, fresh, and confident all day.

Holding up to 100mL, their slimline design fits like a second skin. They’re soft, breathable, and barely-there — and because they’re washable and reusable, they’re a better choice for you and the planet.

Washable undies are designed to fit snugly, so they stay in place and feel secure. If you’re between sizes or prefer a slightly more relaxed fit, we recommend going up a size for comfort.

For the best fit, measure a pair you already own (laid flat) and compare it to the guide below.

All measurements are taken with the garment laid flat (then doubled).

  • Built-in absorbency — four discreet layers for protection you can trust
  • Leak-resistant barrier — stops moisture from escaping, so you can move freely
  • Quick-dry lining — wicks away wetness to keep you feeling dry
  • Odour minimising — powered by bamboo’s natural bacteria-blocking properties
  • Supersoft fabric — made from a bamboo blend to feel gentle against your skin
  • Fully breathable — helps your skin stay cool and comfy
  • Bamboo blend — naturally hypoallergenic & bacteria-fighting properties help care for skin
  • Real underwear feel — exactly like regular undies, just with added protection
  • Lace-inspired detail — because leak protection shouldn’t mean giving up style
  • No-show style — stays invizi-ble under clothing
  • Wear, wash, repeat — machine washable for your convenience
  • No fuss design — goes on just like your usual underwear
  • Reusable by design — washable and built to last for less waste, more wear
  • Responsibly made — crafted with care by makers who value quality as much as we do
  • Free from nasties — made with OEKO-TEX® certified fabrics, no harmful chemicals here

Simply pull these briefs on and off as you would regular underwear. Be sure to machine wash between uses.

 

  • Before first use — Wash in cold water to activate the absorbent fibres.
  • Wash — Machine wash on a gentle or delicate cycle in cold or warm water (below 30°C), using mild detergent only.
  • Dry — Tumble dry on low heat (below 30°C) or line dry in the shade.
  • Avoid — No bleach, fabric softeners, ironing, or dry cleaning.
  • Full Brief only — Remove the pad insert before washing; ensure both are completely dry before re-use.

Frequently Asked Questions

Our Invizi bikini briefs are made to look exactly like regular underwear! Made from a bamboo blend to be comfy and stylish, you'll never know the difference.

You sure can! Be sure to wash them with like-colours on a cold setting (or warm water under 30 degrees Celcius), and skip the bleach or fabric softener.

Our washable bikini briefs can handle light bladder leaks without breaking a sweat.

If you need something that can keep you protected from full voids, we'd recommend trying our disposable option, Invizi Pants, instead.

They sure are! Not only do they reduce waste by being reusable, but they're also OEKO-TEX certified to be free of over 350 substances known to be harmful to human health (that means they're free from things like pesticides, formaldehyde, heavy metals and chlorine!).

Plus, the packaging is FSC Certified, which means another win for eco-consciousness.

    Beautiful feel and fit with ample absorbent padding

    Lovely soft, stretchy outer bamboo fabric & lace. Looks like pretty underwear. Thick inner padding from back to front gives peace of mind about leaks and looks undetectable under clothing. Great sizing - size M (AU dress size 8-10) fits my tall tween daughter and the stretch fabric will allow it to fit even with some weight gain as she grows. Very impressed with these undies - am buying more!
