The Biodegradable Full Brief has a high waist and full coverage for a smooth, comfy fit backed up by superior protection – and sustainability.       

  • Replace disposable pads and tampons – and change the planet, one pair at a time 
  • Modibodi fits and feels like regular underwear, but has a slim patented hi-tech lining to absorb period blood, light to moderate bladder leaks, discharge and odour  
  • Made from 97% biodegradable materials, including biodegradable & compostable packaging = zero waste 
  • To biodegrade, cut off the waistband and discard into landfill, then bury the main pant in active soil. Both environments offer the perfect conditions for each component to completely break down. 
  • Rinse before use, gentle cold machine wash, hang to dry – then repeat. (No fabric softeners or stain removers please) 
  • Proudly owned and designed in Australia by real people with real leaky bodies 


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

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!

Care Guide

Step 1. Wash before wear! We recommend popping them in the wash before the first wear to activate the tech in the gusset.

Step 2. Rinse in cold water after use <30° Do not soak, just rinse until the water runs clear!

Step 3. Cold wash (now or later). In a delicates bag is even better!

Step 4. Hang dry. Reuse. Repeat! Go you eco warrior!

Step 5. Hold the fabric softener. This reduces the product’s function!

"Modibodi was the best thing that ever happened to me."
