Re-usable chemical heater integrated in a neoprene vest compatible with wet and dry suits. The heat pack contains a liquid solution of sodium acetate in a sealed bag, flexing the stainless steel “trigger” within the sealed container causes a single molecule of liquid to crystallize which starts a chain reaction causing the entire solution to change from liquid to a solid. This phase change causes the pack to heat to 54ºC (130ºF), and the generated heat will last up to 30-40 minutes. By placing the pack in boiling water, the crystals are returned to a liquid state, this process can be repeated hundreds of times.

Scuba diving is a beautiful and exciting sport. We need to be warm to maximize our enjoyment. There are sometimes rough seas, cold water, strong currents, bad visibility, and gloomy weather and sometimes you get cold. There is not much we can do about the diving conditions, but you can always dive warm. The new technology is here and it is for everyone.
