The ultimate in underwater protection and thermal comfort, DUI Hot Water Suits are used primarily for heavy duty jobs - construction, engineering projects, and deep saturation work. Divers in our hot water suits can easily work underwater for long shifts, regardless of the water temperature. In this loose-fitting garment, hot water is supplied to the suit by means of an umbilical cord from a topside heater. The hot water is distributed around the diver's body by means of a tubing network, surrounding the diver with an envelope of warm water. View pricing information on DUI Hot Water suits here
