friendly fungi
Our plastic-eating fungi stay safely asleep and dormant in the HIRO Pouch until they come into contact with your baby’s pee or poop.
HIRO Diapers
HIRO Diapers are the world’s first truly naturally degradable, high-performing diapers — soft on skin, tough on leaks, and powered by plastic-eating fungi to return to the Earth.

Diaper
Dear Parent,
Every baby spends their first 1,000 days in a bleached diaper. Every baby goes through ~6,000 of them. And every single one takes 400+ years to break down.
We saw that and couldn’t unsee it. So we built something better. A diaper where baby, parent, and planet all win. For real.
Only Unbleached Diaper
Softest TruCotton
No Chemical Blue Line (BTB)
Super Absorbent
The HIRO Diaper
(pronounced ‘hero’)
First, we stripped out everything that shouldn’t be there. The bleach. The excess plastic. The toxic blue line. What’s left is soft, clean, unbleached cotton that actually absorbs and prevents blowouts. Made with up to 50% less plastic.
The first and only unbleached, high-performing diaper on the market. Made with family-run American cotton farmers.
Diaper and Wipes made with Unbleached Cotton
Super absorbent leak protection for up to 12 hours, day or night
Hypoallergenic and Dermatologist Tested
Mycodigestible™
(aka digested by fungi)
Nature’s Magic
Then, we started working with top nature-loving scientists to help solve the waste that diapers leave behind. We looked to nature and discovered
(and yes, they are natural & super safe!) that can break down plastic! We spent the last 4+ years figuring out how to put sleeping fungi into a little Myco-Pod that you can add after every diaper change.
UP TO—
50%
less plastic than leading brands
(only where performance matters)
5X
drier than leading brands
3X
faster absorption than eco diapers

How Does It Work?
Every HIRO diaper comes with a sidekick: the HIRO Myco-Pod, a cozy home for the friendly fungi. They stay dormant until your baby adds a little stink. Then? Showtime. Toss the pouch in with the diaper and that’s it.
with our vision to break it down. Sustainable. Low-effort. Very magical.
Nature takes it from there,
Our diaper is separately accompanied by a special strain of fungi that have evolved to eat plastics. While the fungi are so safe and friendly (and even edible!) (but pls don’t eat them) they are not in the diaper at all.
Each HIRO Pouch contains a proprietary blend of shelf stable SuperHIRO Fungi, that when discarded, can activate in a couple of weeks. HIRO’s vision is to break down soft plastics in under 12 months in landfills.
Place the whole HIRO Pouch into soiled HIRO Diaper (no need to open it). That’s it. Let nature take it from there.
How it works
How it works
Remove the soiled diaper.
We designed the HIRO Diaper to be the least processed for the baby and also for the fungi to recognize it as food. Unbleached cotton, way less plastic (only where performance counts), NO toxic blue line (aka wetness indicator).
Drop in the MycoPod™
There are NO fungi in the diaper. Instead every HIRO Diaper comes with a sidekick: the HIRO Pouch, a cozy home for our friendly fungi. Just toss the pouch into the soiled diaper during changing time.
Throw it away like normal.
No special throw-away steps, simply toss into the garbage and wait for our friendly fungi to wake up, and in a couple of weeks start working their magic. Saving the planet has never been easier.
Let the fungi do its thing.
When it ends up in a landfill, nature takes it from there, with our vision for the diaper to fully breakdown. Sustainable. Low-effort. Very magical.
DON’T TAKE IT FROM US
Hear what real parents have to say:
“I feel so good that this diaper works and my baby’s poop is fertilizing fungi the help with the plastic problem! It feels good on every level.”
“10 out of 10 I choose HIRO Diaper on how it performed on my twins and for how good it makes me feel not to be generating double the waste.”
“As a master father of four kids,
this diaper is phenomenal — two blowouts and a pee and it worked beautifully. Plus, I feel so much safer for my children’s future.”
6,000 diapers.
One sculpture.
One baby. ~6,000 diapers that take up to 500 years to break down. HIRO built a rolling sculpture out of them and sent it across America to make that number impossible to ignore.
The first step to changing something is actually seeing it. That’s what this tour is for.
Easy Elimination Communication (EasyEC™)
Yes we’re a diaper company, but we’re not here to sell you more diapers.
EasyEC is learning your baby’s cues so they go in a toilet instead. Less waste, thousands of dollars saved, and out of diapers way sooner. HIRO teaches it free, every month.
