A very warm, liquid filled bag that fits into a neoprene belt. You wear this under your wetsuit around your waist to keep your kidneys warm on those chilly days!
What the Australian inventor Chris Lyons says about it:
“The key was to design an underwater personal heating system that was suitable for a whole range of cold water activities. Creating an affordable accessory that could fit people of all sizes and that could be used with any existing wetsuit on the market were all important factors to consider”.
How does it work?
Firstly you have to boil the hot belt in a pan of water for 15mins. But don’t worry; you don’t need a portable stove for the beach! You do this at home and then when you are semi-naked about to don the ole wetsuit, you press the magic button in the middle of the kidney shaped bag and heh presto, weird stuff happens to the liquid (it crystallizes) and the bag’s warmth is activated. It should stay warm for an hour.
Does it work?
In a word – yes! We followed the instructions on the liquid filled bag and boiled it up nicely on the hob. We then let it cool whilst driving to the beach and then pressed the ‘magic button’ and it radiated warmth once inside the neoprene belt. Without the belt it would, one, fall down your wetsuit leg and two, be too darn hot!
We gave it to a lady sailor to try who was moaning about the cold north-west wind on this chilly December day and wasn’t going to go sailing. However, with the hot belt applied under her 5/3 wetsuit, she remained out for at least an hour and although she came in complaining about her cold toes, she said her body was nice and warm and she had a rather red glow to her cheeks! The Hot Belt was only just losing its heat by the end of her session.
Do you need one?
The Hot Belt takes the edge off those really cold days when you just can’t seem to stay warm. If you spent the money on boots, a hat and even gloves, you may well have been better spending it on one of these and not scaring any passing children on the beach looking like Darth Vader. We thoroughly recommend them.
