The inventors of the Heated Wetsuit and series winner on last years New Inventors TV Programme have just finished developing a Heated Kidney Belt which can now turn any wetsuit into a Heated Wetsuit.I don't expect any self -respecting Laser sailor would ever use one of these.
How does it work? It has a built in reusable chemical heat pack which can be activated through your wetsuit when required by locating and then pressing an activator button.
A chemical reaction (phase change) will then provide an instant heat of 50C/122F.
The pack remains warm for up to an hour and can easily be recharged after each surf and sail by boiling it in water for 15 minutes. This process can be repeated hundreds of times.
Chris Lyons, founder and inventor of Hotsuits says "We wanted to change the way you think about cold water forever. It's a fact that when your body is subject to prolonged exposure in adverse conditions it will inevitably lead to heat loss. Using an external heat source assists in maintaining the core temperature allowing you to remain in the water longer even in the coldest conditions."
