Beat the after-drop with a cotton/lycra core-warmer

Product information

A key bit of our winter swim kit - Core-warmer or Haramaki. Also known as: kidney warmer,  belly-warmer, bump band, tummy tube, body warmer, back-warmer...

The haramaki is a traditional Japanese item of clothing. A tube of soft, stretchy fabric that you pull on and wear around your middle. This 'core warmth' effect spreads to the rest of the body. Fantastic for a quicker recovery when getting out of the sea. Helps with the 'after-drop' effect of cold water swimming and allows your core temperature to recover in less time. 

These haramaki core-warmers from Brighton based sea swimmer NukuNuku will keep you warm and keep their shape wash after wash.

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 and cover your muffin top when required! Warning, you can become addicted - we wear ours 24/7 outside of summer...

Made in the UK and built to last from high quality soft cotton/Lycra (92% cotton, 8% lycra 190gsm).

I was sceptical at first but now I swear by these. They can make all the difference when warming up after getting out of the water. Great for period pain too! Shove a mini hot water bottle in there...fantastic.
