Find the perfect Modibodi style for you 

So, you know that a bikini cut is the right style for you, but you’re not sure which level of absorbency you need. No worries! Take our product quiz now and find what your perfect pair is. We’ll take into account what leaks you’re most concerned about, from sweat to incontinence and periods, guiding you to find undies that can replace your current pads, panty liners, tampons or menstrual cups for good.  

Like to mix it up a little? Our range of underpants has plenty to choose from. Our full brief will hold you firm in all the right places, or try our range of French cut leak proof undies for a sensual edge. If you like a little extra coverage, our collection of boyleg knickers have got you covered (literally)!

Modibodi period bikinis for maximum absorption

When we say our period-proof bikinis won’t leak, we mean it. Our patented Modifier Technology combines very thin layers of natural merino wool and microfibre to create a slimline, barely-there pair of undies that can absorb fluid and still feel dry and fresh for hours. We offer a range of absorbency levels, so you can choose the right style for you.

For controlling sweat and handling high-pressure situations with ease, try our moisture-wicking absorbency for all-day freshness. Our super-light and light to moderate levels will keep you dry when dealing with discharge, light bladder leakage and spotting or light flow. If you find you need two or three tampons to see you through a day, the light to moderate and moderate to heavy levels are perfect for worry-free wear all day. Our heavy to overnight level makes sleeping through the night a leak-free dream, while the Maxi-24 hrs offers our highest level of protection ever – able to absorb and lock away up to 50ml of liquid, or the equivalent of 10 tampons.

You can reuse them again and again, so you’ll save both money and the planet when you ditch single-use products for our clever design.

Frequently Asked Questions

Do I wear these with a tampon, cup or pad?

Modibodi are a complete replacement for other leak management products. There is no need to use anything else in conjunction with them, even on your heaviest days. With absorbency options ranging from super light through to maxi-24hrs, you can feel confident every day, flow or no flow!


What size am I?

We always recommend taking your normal underwear size. 

Do I need to wash them before wear?

Yes, we recommend putting them through the wash before the first time you wear them to help to activate the technology in the gusset.

What does it feel like wearing them?

Just like regular underwear! Our tech-enabled absorbent gusset was designed to be comfy and discreet, never bulky or heavy. Just pop a pair on and go!
