Ember Patch uses natural, air-activated heat technology to provide soothing warmth wherever you'd like it. Once the sealed pouch is opened, oxygen reacts with the ingredients inside the patch to generate a steady, comfortable heat that lasts for up to 8 hours. Simply open the pouch, peel the adhesive backing and place where you'd like the warmth. Once finished, peel it off residue-free.

  • In the box: 6 individually sealed patches, easy to keep one in your bag
  • Patch size: 17.5 cm × 8 cm
  • Warmth: around 41°C
  • Lasts: up to 8 hours
  • Warms up: reaches full warmth within 10 minutes of opening
  • Shelf life: 3 years unopened
  • Storage: keep sealed until you're ready to use it, at room temperature
  • Once finished: the patch isn't recyclable and goes in general waste, but the pouch and box are recyclable

Just four things, held in a non-woven fabric shell: iron powder, salt and water, and activated carbon. No fragrance, no medication, nothing you can't pronounce.

Patch-test before your first use, don't apply it to broken or irritated skin, take it off if it ever feels too hot, and don't wear it while you're sleeping. If you're pregnant, or managing diabetes or circulation issues, check with your doctor first. Keep away from children and pets. Single use, one patch, one wear.

We ship right across Australia and New Zealand. Once ordered, it will be processed within 1–3 business days. Once your order is shipped you'll receive a confirmation email with a tracking number. Estimated shipping time is 5–7 business days across Australia and New Zealand.

We understand comfort feels different for everyone. That's why with our 60-day money back guarantee, if Ember Patch isn't quite right for you, get in touch within 60 days of receiving your first order, and we'll refund it.

I forgot I was wearing it

"I wore it through a full day at work and honestly forgot it was there. It sat comfortably under my clothes, stayed in place, and kept giving warmth for hours."

Natalie

it's so comforting

"The warmth felt really gentle, comforting and consistent. It never got too hot. I could place it exactly where I wanted it and just get on with my day."

Manith

so much easier than a hot water bottle

"I usually use a hot water bottle, but waiting for the kettle and reheating it can be annoying. With Ember, I opened the pouch, put it on, and it started warming without me having to do anything else."

what's inside

  • 1

    air gets in

    Opening the pouch lets air through the breathable top layer to the ingredients inside, and the warming begins.

  • 2

    a natural reaction begins

    Iron powder reacts with oxygen (oxidation) and releases heat. Salt and water keep the reaction moving, while activated carbon spreads the warmth evenly through the core.

  • 3

    steady warmth, up to 8 hours

    The blend and breathable design control how fast oxygen reaches the core, so the warmth builds gradually and stays steady instead of spiking.

Made with naturally derived ingredients.

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,

what people are saying.

the honest answers

what people ask.

Apply it to skin on your lower tummy, lower back, shoulders or neck, wherever you'd like the warmth to sit. It's slim enough to stay hidden under your clothes.

It's slim by design, so it sits quietly under most outfits. You'll feel the warmth, but you'll forget it's there, that's the whole point.

Up to 8 hours of steady warmth from a single patch.

Ember is designed to be gentle on skin, but there are a few times when warmth should wait, and a few simple rules keep it safe for you. Patch-test before your first use, don't apply to broken or irritated skin, take it off if it ever feels too hot, and don't wear it while sleeping. If you're pregnant, or managing diabetes or circulation issues, check with your doctor first. Keep away from children and pets. Single use.

Our orders are quickly processed within 1–3 business days. Our estimated shipping time is 5–7 business days across Australia and New Zealand.

It's a fair question, and one we think about. Each patch is one wear, and we're honest about that. Our patches are made with naturally derived ingredients, and the packaging is 100% biodegradable and compostable. We're always working on the most responsible way to handle our materials as we grow.
