ember patch worn low on the tummy

what it is

the hot water bottle you can wear.

A slim, self-warming patch that sits low on your tummy, your back or wherever it hurts. It warms on its own the moment it meets the air, then stays with you through work, a festival, or a day on the couch.

  • ~41°, gentle and steady
  • up to 8 hours of warmth
  • warms on contact with air
  • fragrance-free, non-medicated

the first batch

why only 300?

This is our first production run. Three hundred is what we could make, test on real people and pack ourselves in Melbourne without cutting corners. So the first 300 orders get three patches free, and you only pay shipping. When they're gone, the next batch lands mid-November.

why we started ember patch

We're two guys, so we won't pretend to know what a period feels like. What we did see was the people we love, spending their period days on the couch with a hot water bottle, waiting for it to go cold. The thing that comforted them most was the same thing keeping them home. So we set out to make that warmth portable, and we tested every batch on the people it's actually for.

We don't have 80,000 reviews yet, and we're not going to fake a single one. What we can promise is that we sweated the small stuff, and we'll keep listening.

keep warm,
harry & aaron

good to know

questions, answered.

when does it open?
Soon. We'll email the list first, before we post the link anywhere else. If you're on the list, there's nothing to refresh or race for.
how much is it?
The first 300 orders get three patches free and pay shipping only, $9.95 in Australia. After that, a box of six is $35, two boxes are $66 with free shipping, and three are $90.
where do you ship?
Australia and New Zealand. We pack every order ourselves in Melbourne and dispatch within 1–3 business days. Standard shipping is $9.95 in Australia, and free on orders over $50.
what's in it?
Iron powder, activated carbon, salt and water, sealed in a slim patch. It's non-medicated and fragrance-free. Open the sachet, air gets in, the iron warms up, and you get around 41° of steady warmth for up to 8 hours.
is it safe?
Do a quick patch test the first time, take it off if it feels too hot, and don't wear it while sleeping. If you're pregnant, or managing diabetes or a circulation condition, check with your doctor first.
