Description
Description
Kosi is a 360 degree, hands-free heat pack that wraps around your torso for complete heating and relief. The only heat pack you will need each month so you can get on with your day!
Kosi is filled with Flaxseeds. Flaxseeds are reported to have pain-relieving and anti-inflammatory properties to provide you with an extra soothing affect. The filling has a really slight, pleasant earthy smell that you will barely notice. No wonder Kosi is your bellies bestie!
Kosi can be worn at home, the office or as you go about your day. It can be worn over or under your clothes - it can be our little secret! However, many people like to take advantage of our Bestie Bundle. This will allow you to keep a Kosi handy at both work and at home, so it is always by your side when you need it.
Microwave Use Only: Follow Heating Instructions Carefully, Avoid Overheating.

Kosi is made of soft plush polyester fabric to ensure it is gentle on your skin, heat resistant velcro and is filled with flaxseeds. Upon heating the flaxseeds will release a small amount of flax seed oil which will assist with extra relief.
Heating Instruction
Heating Instruction
1. Please cover the wrap in a wet towel before heating. Place room temperature wrap evenly spread in the centre of a clean microwave turntable, not touching the sides of the oven. Ensure that any additional microwave features are turned off, such as "browning".
2. Heat in the microwave for 60 seconds (800W) or 40 seconds (1000W). Flip inside out and upside down, giving the product a good shake, and heat for a further 60 or 40 seconds. If reheating, heat for an additional 15 seconds (800W) or 10 seconds (1000W). Please do not exceed 180 seconds total heating time.
3. Check to ensure temperature is suitable before application. Before reheating, check if the temperature of any part of the pack is too hot. Knead and rotate the pack to disperse heat evenly.
What is the difference between Kosi and Ziggle?
What is the difference between Kosi and Ziggle?
Ziggle is slimmer and 200g lighter, perfect for wearing under your clothes. Kosi is like wearing a big warm, puffy cloud. Ziggle's unique zig zag stitching stops the fillings from sliding down as you go about your day.
We recommend Kosi for lounging at home and Ziggle for the office. We recommend Kosi queens make use of our Bestie Bundle so Kosi is always with them when they need it ❤️

This product is the best
Hi Luke, we love hearing this and thank you for sharing! We're so happy she's loving her Kosi and that it's been such a big help. It means the world to us! <3
Comfortable to wear, but it definitely doesn’t get hot enough or stay hot for long enough. I’ve overheated it as well but still same result
Hi Jasmine, thank you for your feedback and we’re really glad to hear you’re finding it comfortable to wear. Kosi is designed to offer around 20–30 minutes of gentle, wearable warmth, but microwave wattage and heating method can make a big difference. We’d love to help troubleshoot your routine to see if we can improve your experience! Feel free to reach out to us at info@kosi.au and our team’s always here to help. <3
Love love love. I wish I'd brought it earlier.
Hi Emma, so glad you’re enjoying your Kosi and we’re so happy you received your Kosi. Thank you for the kind words! <3
I have purchased other products from other shops and they were terrible compared to this product it focuses on everywhere because it wraps completely around.
It would be good it stayed hotter for longer but compared to other brands this one is 10/10
Hi Yazmin, thank you so much for your kind words and we’re so happy to hear Kosi has stood out from the rest and is giving you that full wrap-around relief, that’s exactly what we designed it for! Kosi is designed to provide around 20–30 minutes of gentle, wearable warmth. If you're open to it, we’d love to help troubleshoot the heating process to see if we can improve the results. Please feel free to reach out to us at info@kosi.au and our team is happy to help! <3
