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 Mycelium to return to the Earth.

HIRO is on a mission to help solve the global plastic crisis, starting with the #1 household plastic waste item: diapers.

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.

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.

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
friendly Mycelium
nature magic

Our plastic-eating Mycelium stay safely asleep and dormant in the HIRO Pouch until they come into contact with your baby’s pee or poop.

(and yes, they are natural & super safe!) that can break down plastic! We spent the last 4+ years figuring out how to put sleeping Mycelium into a little Myco-Pod that you can add after every diaper change.

Mycodigestible™ = digested by Mycelium

How Does It Work?

Every HIRO diaper comes with a sidekick: the HIRO Myco-Pod, a cozy home for the friendly Mycelium. They stay dormant until your baby adds a little stink. Then? Showtime. Toss the pouch in with the diaper and that’s it.
Nature takes it from there,
how does it work

Our diaper is separately accompanied by a special strain of Mycelium that have evolved to eat plastics. While the Mycelium are so safe and friendly (and even edible!) (but pls don’t eat them) they are not in the diaper at all.

with our vision to break it down. Sustainable. Low-effort. Very magical.

Each HIRO Myco-Pod contains a proprietary blend of shelf stable SuperHIRO Mycelium, 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.

HOW IT WORKS

1. Remove the soiled diaper.

We designed the HIRO Diaper to be the least processed for the baby and also for the mycelium to recognize it as food. Unbleached cotton, way less plastic (only where performance counts), NO toxic blue line (aka wetness indicator).

2. Drop in the MycoPod™

There are NO mycelium in the diaper. Instead every HIRO Diaper comes with a sidekick: the HIRO Myco-Pod, a cozy home for our mighty mycelium. Just toss the pouch into the soiled diaper during changing time.

3. Mycelium take it from here.

No special throw-away steps, simply toss into the garbage. 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.

ONE ISPIRED ACTION

Place the whole HIRO MycoPod into soiled HIRO Diaper

(no need to open it). That’s it. Let nature take it from there.

DON’T Just TAKE IT FROM US

“I feel so good that this diaper works and my baby’s poop is fertilizing Mycelium to help with the plastic problem! It feels good on every level.”

JOEL + ILANA, TX

“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.
