The haramaki is a traditional Japanese item of clothing worn under or over clothes around the middle to keep you warm. Unisex and ageless - for anyone who wants to banish the cold. We took this Japanese idea and made NukuNuku's own brand single layered soft cotton haramaki will keep you warm and keep its shape wash after wash. Wearing our tummy-wrap will keep your core warm and allow your whole body to stay warmer.

Great while pregnant to make your clothes fit you longer by layering and post-partum to make you feel held or warmer when breastfeeding.

May aid digestion and ease lower back pain, covers you up during sports such as pilates, cycling and yoga and allows you to stay outside for longer. Warning, you can become addicted - we wear ours 24/7...

Our own brand NukuNuku haramaki are single layered and average 30cm from top to bottom, covering your kidneys and lower back to top of the hips. 

Sceptical and think you dont need one? You may be if you havent yet tried them (but you will be hooked when you do!) You can test it out by tying a scarf round your waist to try the effect. Soon you will see that having the core of your body insulated raises your body temperature all over. This is because the inner organs are warm, increasing your circulation, which spreads heat all over your body, even to the toes and fingers.

Don’t take our word for it, please take a look at our reviews:

“I have been wearing haramakis from NukuNuku for several years now and wear them most days. I find that they have helped with so many things and recommend them often to my acupuncture patients (both female and male). They have reported back saying wearing them has helped with issues such as lower back ache, occasional bouts of sciatica, women's issues, supporting those with weak bladders, digestive issues and are great to wear to bed when camping! From my experience, they wash well and keep their shape and come in lovely colours. Thanks for a great product”

“The Haramaki changed my life, you have to try it. This Haramaki is absolutely perfect on the body, cotton and feels great against the skin. Keeps your core warm in a way that I thought it couldn't be possible (but is never too warm at the same time). It is a must have, give it a chance. Helped me with keeping my core warm, my menstrual cramps, my energy levels... 10/10. Thank you!”

Also known as: kidney warmer, belly-warmer, bump band, tummy tube, body warmer, nierenwärmer, back-warmer, core-warmer....

* we are aiming to make all our black haramaki from organic cotton

I love it....such a simple idea and perfect for everyone of my outdoor pursuits!

Super fast and efficient delivery, with recycled packaging.

Saving for my next one!

I was given a haramaki kidney wrapper for Christmas and very much appreciate this light extra layer of warmth. It also has another very useful function.

I have a small metal healing plate 2.5 x 2.5 x 1/8th inch, ( not an electrical gadget ), which helps to reduce arthritic pain. It has to be in immediate skin contact. I have had an allergic response to medical tape which I used to keep it in situ. I now overlap my harimaki around my hip before sleeping and tuck the plate down inside it and it usually stays snugly in place. Next morning I can open it out and use it as a kidney wrapper again. It washes and dries easily and quickly. What a useful and simple thing it is.

Having been introduced to the concept of a haramaki many years ago, I tried a couple of different suppliers out, but then I found NukuNuku. I've never looked back. As someone who is tall, I've used them for years to keep warm and prevent drafty gaps between layers, but recently I've found them to be INVALUABLE as a breastfeeding mother. They give my mid-rift a warm, cosy feeling, wrapped up like a hug, and means I can wear whatever clothes I like and still keep cosy whilst feeding. I cannot recommend them highly enough.

Just to thank you for the excellent service and to say how pleased I am with the Haramaki it will be perfect for my cycling. Your size suggestion was spot on and I will be ordering another in the near future

Kept me warm at a festival this summer when the temperature dropped. I usually wear it as a boob tube but was very glad to have it as an extra layer keeping me warm. Thanks to my Mum for getting it for me!
