It arrived quickly, just in time, and I must so say, I'm loving it ; its so comfortable and easy to heat up. I love it how its handsfree so I can just sit back and relax. (somewhat, :P) highly recommended to anyone who suffers back and period pain. . Thank you so much, KOSI, a definite life saver.

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!

Product itslef is great. But the velcrow is scratchy if it’s against skin and it doesnt heat up enough for me.

I bought the endo bundle and the heat packs don't heat up at all and because you need to use a wet cloth it comes out soggy. I sent an email to the team and they just repeated the heating instructions which didnt help at all.

The tshirt was not my cup of tea. The fabric made me feel weird and uncomfortable.

I have severe endometriosis and adenomyosis on top of terrible period pain. This has been a game changer because I can get heat to my back and stomach simultaneously. It is comfortable and soothing. I would definitely recommend it.

So comfortable and easy to use. Came quicker than expected and beautifully packaged. I especially appreciate the care that has gone into the design of these heat packs!

So great during a flare so I can still move around.

I suffer stage 4 endometriosis, I stumbled onto Kosi on instagram one day when I was scrolling. I had another Endo surgery coming up and I seen they had ‘the ultimate endometriosis bundle’, I was curious so I started browsing. I was telling my Nan about it and next thing she had ordered it for me, agreeing it would be perfect for my Endo. I live with at least 3 heat packs glued to me at all times.. but not anymore. I use the Kosi wrap and the neck and shoulder heat packs. I have never had gas pain after surgery disappear as quickly as it did when I started using the neck and shoulder heat pack. And being able to have 360 degrees of heat, and it be stuck to me without moving as I moved around, made this recovery process so much easier. The sleep shirt is a must for all the Endo belly sufferers out there.
You need this in your life!

Barely lasted a couple of months. Kosi split after less than a dozen uses after heating for 2 minutes in the microwave.
Customer service was quick to blame - unapologetic and refused any compensation. Do yourself a favour, choose a company that produces a quality product they are willing to stand behind.

Helps me so much! Best purchase I’ve made, I’ll use it while I’m driving or while I’m working and even just when I’m laying down, love it!

Absolutely amazing and perfect for helping us chronically ill girlys. Would highly recommend.

I recently purchased this endo bundle as i have terrible period pain and very tense shoulders! Since this purchase i have had ankle surgery and spent alot of time in bed resulting in an incredibly sore lower back. The kosi has been an absolute life saver for this lower back pain. Highly recommend!

The heat doesn't stay for too long. It needs to be heated for 3 minutes for it to actually feel warm enough and then it stays for only few minutes. Definitely not enough to manage endo pain. The wrap around design is good and I really wanted it to work but unfortunately doesn't meet that expectation.

It’s convenient to wrap around your body but other than that I’ve had better heat packs. It doesn’t stay warm for long at all. I had to reheat it every 15-30 minutes.

I was recently diagnosed with Stage 4 Endo, and began researching more about the condition, and came across Kosi. This is a game changer! I got my Endo Bundle, and oh my god. Pure Heaven! Where have you been all my life?!

Absolutely love the kosi kuddle tee, so soft!! And it has pockets!!

Omg this is the best heat pack I've ever owned and ive owned alot of them .. love the convenience of been able too walk around with with and love being able too heat all the way around my abdominal around .. thank you soooooo much 😘 💖

I bought the bundle in black after seeing advertisements for a bit and enquiring about whether I can wear it low on the pelvis as thats where the pain is debilitating for me. Everyday for the past 2yrs I've been walking around with a heat pack tucked into the front of my undies and a heat pack in the back. They were lumpy, kept falling out and I could only wear them at home (which meant gritting teeth to cope during the day). I purchased the endo bundle as I'm going in for my first endo surgery soon and thought I should treat myself.... best decision ever! The material is excellent quality, the heating does take some getting used to but I can wear the wrap all night without reheating, and it doesn't slide around (I'm an extremely restless sleeper)! The shoulder heat pad hits all the sore spots in my neck and I can work comfortably with it on under my shirt without the risk of it falling off. My one note is that, as a disabled person living with one hand, the velcro is super strong and quite difficult for me to open and close the waist pack though, I expect this to wear down over time. I've worn it almost non stop since it arrive and it's made functioning a little easier.

...I think the only problem is that I'm going to have to order another bundle as my dad keeps stealing it because it targets his pain as well!

Adore the product, I love it and have raved about it ever since using it.

This book is so sweet, I don’t know if validating or empowering is the right word to use? It makes you feel seen with the messages and pictures in this book. The pages are a little thing so my felt tips leaked through but all in all it’s super cute

While I’m very new to my endo and adenomyosis journey, I have relied on regular heat packs for years and years and they just don’t cover enough of the crampy spots, they’re also super awkward to have to hold against my tummy and carry around the office at work. I am obsessed with my ziggle! I’ve heated it up a few times now and notice the more I do it, the longer the heat lasts once the flax seeds start doing their oil thing, just like the info says! It covers all my regular pain points, as you’d expect being a wrap around heat pack and the weight of it is a comfort too! Thank you so much Kellie and team! Best purchase!!

I found that they don’t stay warm very long and I have to reheat it every 30 minutes for my daughter.

I love my Kosi. It’s my endo friend I call it. It’s brings me comfort while helping with the pain from endo , adeno and pcos! Amazing work to the Kosi team. 💛

Amazing product! Soooo happy!
