Flow: 15ml = 2-3 tampons or 3 teaspoons 
For: Moderate to heavy periods, light to moderate bladder leaks or discharge  
Feels:  Soft, luxe & comfy with trusted leak-proof protection  
Impact: Zero waste! A planet-friendly replacement for pads & tampons that’s also 97% biodegradable 

Feel good about your period and pee-proof undies with our Biodegradable Full Brief. 

An absolute game-changer, our biodegradable underwear doesn’t just help the environment by replacing disposable pads, tampons and liners with a trusted leak-proof lining...it’s made from innovative biodegradable materials designed to prevent textile waste piling up in landfills.  

They’re super soft and just as comfortable, reliable and effective as the rest of your Modibodi undies. Only... better for the planet! 

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

 Rinse

Rinse your used underwear in cold water after use <30° Don't soak, just rinse until the water runs clear.

 Cold wash

Cold wash (now or later) In a delicates bag is even better. Avoid any fabric softener.

 Hang dry

Hang dry. Reuse. Repeat. Easy done.

Comfortable and high quality

Pleasant, high quality fabric. I like that it’s high waisted because it keeps my stomach warm which reduces cramps for me. I found the sizing to be on the larger side compared to Classic Bikini and Thong. I got M (EU40) in all and while the bands of the Classic Bikini and Thong cut into my sides quite a bit, this one fits nicely.

For reference I’m 170cm tall, weigh 68kg, my hip circumference is 102 cm.

My favorite underwear out of all I own

The tencel/wool blend is so soft and cozy. After trying these on for the first time, I went nuts trying to find non-period underwear and even clothing with a similar composition because it's just THAT comfy. The only reason I look forward to my miserable periods is so I can wear these. The only downside is that they take the longest to dry out of all my Modibodi underwear, but it's well worth it and I plan on buying more!
