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. It has been called a boob tube for your middle. A 'core warmth' effect spreads to the rest of the body. Fantastic for a quicker recovery when getting out of the sea. Helps with the cold that comes after swimming when you continue to cool after getting out by layering you up quicker. You can stuff a hot water bottle down it for extra warmth and it will hold it in place.
These haramaki core-warmers from Brighton based sea swimmer NukuNuku will keep you warm and keep their shape wash after wash.

Sceptical and think you don’t need one? You may be if you haven’t 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.
