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....

Toasty all day!

It takes a bit of time to get used to it, but after that you will forget it's on and just be nice and toasty!

The best thing I've bought!

It is an absolute necessity for anyone in this weather! Yes, it's been mild so far but if you're a bit on the skinny side, like my daughter you're always cold no matter the temperature! I recommend this for everyone!

It keeps you warm 😊

I'm a long-term convert to the haramaki, and bought this for my sister

Extra bit of warmth

It is lightweight and great for those times when it is not freezing outside but I need an extra bit of warmth. I wear it to play tennis in the winter and it means I can dispense with a jacket which constricts me.

Keeps you warm where you need it

Having put on weight during lockdown, I noticed a lot of my T-shirts were no longer tuckable and were creeping up my back. This left my lower back exposed and prone to chills in my kidneys. This product perfectly solves this problem. It's stretchy enough to fit most waistlines and comfortable enough to forget it's there. Good price, high quality. If you have a similar problem, THIS is the solution.
