With the ability to absorb 20 ml of fluid, which translates to three or four tampons worth, you’ll never need to fret about ruining your white sheets again!

Underwear with Heavy-Overnight absorbency is ideal for people who move around while they sleep or can’t always get to a bathroom right when they need to. Now you can stay on the go without needing to check for accidents, get a few extra Zzzs in the morning, or indulge in that extra-long walk, confident that you won’t be bothered by leaks or odour.

Advanced technology to provide leak-proof protection

Our patented technology gives Modibodi Heavy-Overnight undergarments their stellar absorbency and ultimate comfort. Get rid of pads, liners and tampons that contribute to dangerous waste disposal levels and say hello to the new way to remain cool and dry. 

With a top layer that wicks away moisture, our Heavy-Overnight absorbency underwear traps fluid in the centre of the super lightweight fabric while the outer layer gives you additional defence against leaks and feels wonderful against your skin. The best part is, they’re easy to wash and easy on the planet — that’s what Modibodi is all about.

All about your new favourite products

In addition to our Heavy-Overnight absorbency underwear and other underwear ranges, we also offer a gorgeous line of absorbent maternity wear, including our Maternity Brief, Postpartum Support Brief and Breastfeeding Bras and Camis. The Modibodi Maternity Collection makes a fantastic gift for new mums and mums-to-be. 

If you have young ladies in the house, you'll definitely want to check out our leak-proof underwear and swimwear for tweens and teens. Our newest addition is a high-cut style that's just made to go under apparel for dance, gymnastics, skating, and acrobatics. 

We also have a men's collection — offering briefs and shorts that provide the same supreme dryness and leak-proof technology. Gents love them for catching sweat and other drips — whether on a hot day or after surgeries. 

Our Reusable Baby Nappies use the same technology as our Heavy-Overnight absorbency underwear to trap liquid and prevent leaks — and they’re good for Mother Nature too. Sized for babies through to toddlers, our easy-to-wash nappies use a biodegradable liner to handle number twos and keep little ones' skin dry and free from chafing whilst combating odour and bacteria. 

When you purchase from Modibodi,  you're buying from an environmentally-conscious business aiming to make a difference in the world. Take advantage of our free shipping on orders over $100 and our 60-day risk-free trial policy today.

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!
