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....

Love it for the colder months

I hate my back to be even the least bit bare and cold when my jumper/top isn't long enough for when I sit down or bend. I've just realised I can't find my Black Haramaki I ordered a few months ago, ordering a new one. Even if I find the first one eventually, won't hurt to have two. Highly recommended.

Excellent service

Spot on product!

I bought my haramaki on the advice of a fellow swimmer and I'm so glad I did. Swimming daily in the lido is getting a bit 'fresh' so to add a discreet extra layer around my lower back and stomach is wonderful. Makes it even better when you add a small hot water bottle to the equation which is neatly held in place by the haramaki! I can see how this would be brilliant for anyone working outside like a gardener and cyclists too, well pretty much anyone. I wish I'd had one earlier in my life.

Haramaki Convert.

The haramaki has made an instant impact on my core warmth, complementing the acupuncture treament I am having. I am going to order 2 more but in a smaller size for a firmer fit. I have recommended this item to 2 people, one with Rheumatoid arthritis and one who does cold water swimming. I am also please that it is made in the UK. The service, delivery and communication made it a straight foreward purchase online.
