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.

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 damp 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". Please do not heat Kosi in an oven or a convection oven/microwave as this will cause burns and damage to the product and could be hazardous.
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.

Really wonderful product and helps a lot with pelvic pain. The only downside I have found is that it takes longer to heat than my usual heat packs. That said, I would definitely recommend it for my endo and adeno girlies x
Awesome heat pack!!
The perfect hot pack trio.
As someone who has had 2 previous spinal fusion's and endometriosis these heat packs are absolutely perfect, with the material being super soft and not scratchy. I dont feel weighted down with them at all. They sit comfortably and with the Velcro in three different spots it really helps the hot pack to stay where you need it.
Thank you so much to the lovely team ❤️
Works absolutely fabulously.
Love this product! Easily covers back & hips, comfortable & soft.

I’ve genuinely really enjoyed using Kosi! It’s become such a nice little part of winding down at the end of the day, especially after a busy day of mum life 😂
I love anything that makes my evening routine feel a little more cosy and intentional, and this has been such an easy addition. The whole experience feels really comforting and like a small moment of self-care that I actually look forward to.
Definitely something I’ll continue reaching for as part of my wind-down routine 🤍
My new favorite addition to every morning and evening. I have had lower back pain for years and also have adenomyosis so abdominal pain and cramping are a big part of my life... this has been an absolute game changer. Highly recommend
Where has this been all my life 😭 since having a baby my ovulation pain is INTENSE and so are those day 2 cramps! From the minute I put this on it significantly reduced my cramps and the best part is it gets rid of the front AND back cramps 🙌 love being able to use it hand free - just put it on and go about your day! Super helpful with a toddler and not being able to lay down for more than 5 minutes. Honestly a game changer 🥰
The product itself is great. I’m just giving 4/5 because the Velcro is insanely strong and the material is very soft/thin (in a comfy way) It tore stitching out on the first use so now the beans kind of bunch up. We’ve started just using a small part of the Velcro instead or maybe we might cut it off. Otherwise is very nice.
Hi Glenn, thank you so much for your honest feedback. We’re glad you’re enjoying the product overall. We hear you on the Velcro, it’s designed to stay secure, but we understand it can feel strong against softer fabric. We’d love to assist regarding the stitching, please feel free to reach out to info@kosi.au so we can take a closer look and support you. <3
this heat pack has changed my life!!!
just had an endo surgery and this is making recovery so comfortable
Hi Emelia, this means everything. We’re so glad Kosi is making your recovery more comfortable. Wishing you continued healing and gentle days ahead. <3
Love the heat pack. I ordered 3 and my girls love them as well. Mine did not come with its carry bag so I emailed asking for it. Was told they would get one out to me asap. That was a month ago and still no cover unfortunately. I would still highly recommend still.
Hi Kerry, thank you so much for your order and for sharing your experience. We’re so happy to hear you and your girls are loving the heat packs! As for the Kosi bag, we really appreciate you reaching out. Just to clarify, the carry bag isn’t officially included with every order and it’s something we occasionally pop in as a little freebie when stock allows. At the moment, we still haven’t received a new batch. We completely understand the wait has been a while, and we truly appreciate your understanding. Your feedback means a lot and If there’s anything else we can help with, feel free to reach out anytime at info@kosi.au.
I got this heat pack as a gift for Christmas and I have never felt such relief. I have endometriosis and I put on the heat pack right after receiving and it literally bro if it tears to my eyes on how amazing this is get yourself one now if you have any sort of bad cramps!!!!
Hi Victoria, we’re so incredibly grateful to hear that your Kosi brought you relief right when you needed it most. That kind of comfort during endo flare-ups is exactly why we created it. Thank you for sharing your experience, sending lots of warmth your way! <3
As someone who suffers from PCOS, Endometriosis and adenomyosis, i had a feeling I’d love this but didn’t realise how much difference it was going to make to my day. It stays in place so much better than i thought it would when I’m walking around. I even tried it with satin pjs and it still stays in place! The only time i take it off is to heat it back up and shower. It’s providing me with so much relief. Thank you so much for creating such an incredible product that makes such a difference!
I’ve tried plenty of methods to manage my endometriosis symptoms! The 360 Kosi heat pack is definitely my go to tool for relief!
I take mine everywhere with me and it’s so easy to use, perfect for women who experience painful periods!
🎗️💛
Thank you so much for sharing this, Lyndall! It means the world to us knowing your Kosi heat pack is giving you relief and making a difference—sending you lots of love and warmth! <3
I like the idea of the product however was disappointed that the Velcro began to come off after 2 uses.
Hi Kate,
Thanks for taking the time to leave us a review ☺️ I'm so sorry this has happened. I can see you have an older model and we have since updated our stitching method. Please reach out to info@kosi.au and we will replace this right away.
Have a lovely day,
Kellie
Dealing with period pain is no joke, especially for us girls with endometriosis! Kosi has seriously been a lifesaver during this time. It really works, trust me! Dont suffer in silence - this is a game changer!
It’s like a brace almost it’s so good! Really does provide almost immediate relief. My lower back is very tight and when due for my period the pain just radiates and with the release of prostaglandins it is honestly horrendous! This has been a huge help 🥰
Thankyou for your amazing feedback! I am so glad Kosi has been helping you <3 Kellie
My right ovary is immobile and suspected to be adhered to my bladder (yay) and the pelvic and back pain is intense!! I love having a heat pack all in one ❤️
Thankyou for your lovely feedback! I am so sorry to hear about your pain, but I am so glad to hear that Kosi is helping.
<3 Kellie
im not usually one to write reviews, but this had to be said. as a young person with endometriosis, kosi is genuinely such a lifesaver! i’ve tried so many heat packs and none of them stay warm, they go cold after 15 minutes, whereas i’ve found kosi stays heated for way longer! it’s helped me get to sleep when i am having awful flare ups, it honestly feels like a warm, comforting hug. Kellie has created the most amazing product, at such a reasonable price too!! I highly reccomend 🥰
Hi Madison,
Thankyou for the wonderful feedback! I am so sorry to hear that you have endo, but I am glad you are loving the heat retention! We use 100% Flaxseeds which are reported to have the best heating properties, so I am really glad it has been making a difference for you.
I hope you are having a lovely day!
Kellie xx
i hadn’t had an endo flare up in two weeks (which is amazing for me) and i was trying to sleep which was hard when your in pain!! but kosi helped so much
ahh thank u so much!!
Thankyou for this wonderful feedback! I am so sorry to hear about your endo, but I am so glad your Kosi has been helping! (please note that we cannot recommend wearing Kosi in bed as the sheets may not be heat safe fabric). I hope your flare-free streak continues :)
Kellie xx
If you get bad period pain or ovulations pain I just ordered this and its a 360 degree heat pack!!! I saw an ad on Tik Tok and got it asap because I swear I have issues like scar tissue that pulls and hurts from after my c section every ovulations and period. Its so good I literally love it!
It's the best thing ever I haven't taken it off since I got home from work thank you so much
I’ve had my Kosi for less than 24 hours and it’s incredible. Even when I’m not using it the way it’s intended, I can lay it to cover my stomach and inner thighs to cover all my pain areas. Also, it’s somehow lighter than my other small wheat packs despite being almost 3 times the size. This is going to make travelling so much easier cos I’ll only need to take this instead of 4 heat packs and it’ll still be much lighter It’s absolutely 100% worth it and also it’s always great to support a fellow Endo warriors business. ALSO! They’re queer friendly and use inclusive language for our Endo siblings who are not women
Thank you!! It’s beautiful, I’ve had my eye on it for ages it’s so helpful!! I love it honestly been waiting for someone to do this.
love it. arrived in time for latest endo encounter
Really wonderful product and helps a lot with pelvic pain. The only downside I have found is that it takes longer to heat than my usual heat packs. That said, I would definitely recommend it for my endo and adeno girlies x
Awesome heat pack!!
