Absorbency: 15ml = 2-3 tampons or 3 teaspoons

Introducing the world’s first pair of biodegradable period underwear. These clever undies are proven to have 97 per cent of its components break down at the end of their usable life - with most of the brief’s materials decomposing within six months when buried in active soil. If that's not enough, they're super soft and comfy too.

  • The Biodegradable Bikini sits on the hip with a high-cut leg for a smooth, comfy fit backed up by superior protection – and sustainability.
  • Modibodi fits and feels like your regular underwear, but with a built-in patented (3mm) lining to absorb your period or pee.
  • A reusable alternative to disposable pads, liners or tampons.
  • To activate your Modibodi’s magic powers, wash before use.
  • Proudly designed in Australia.

CARE: Please read our FAQ for how to wash and care for your Modibodi.

Better than I could've imagined

honestly just so impressed with how comfortable and well these work. My first period undies and not my last--does not feel like a diaper and there is NO SMELL it is wild, but I am here for it! Fit super well, love love love the fabric, breathable and comfortable, and look cute esp for what they are. Does give a panty line due to being thicker for the portion that holds the liquid but expected that and imagine any period underwear that is not a thong will be the same way. 15/10 stars! My waist is actually a 27, but that is not an option, and I think the sizing guide suggested an XS but honestly super happy I went w the small. I got some high waisted ones and the vegan boy shorts and those are a little bit more snug, also got those in smalls. The two of this style I got are my fave, they just feel like wearing nothing and it is lovely!

Did not expect to feel this safe

I was floored. The whole time I wore this, I didn't feel soaked or uncomfortable. It was like I wasn't on my period . I had it on for 10 hrs .

The only gripe I have is it takes a long time to dry especially in Melbourne's unpredictable weather so Id suggest buying at least 4 or 5.

If I have to ,I'll pop in the dryer on the lowest heat setting for 10 to hasten the process but please remember that prolonged usage may reduce the effectiveness of the material. Other wise best decision ever ..

Its light and soo breathable as well.

Very comfortable

I love these. I compared these with Thinx and Period brands ans these were my favourite. They were the least bulky and most absorbant.
