Heated undergarment for cold waters -- comes with socks and gloves.

The BlueHeat liner is a lightweight and comfortable jumpsuit made with soft next-to-skin fleece and lycra outer for easy donning and doffing, and has anti-microbial lining.  This heated undergarment offers torso warming in three output options: 50, 75, and 100 percent. 

Safety and protection is ensured by encasing BlueHeat wiring ( industry leading / high strand Microwire®) with a thermal protective jacket. Additionally, internal heating pads have independent thermostats and diver protection circuits.

Technical divers have understood for decades that passive insulation is not always enough for ultra-long underwater exposures. As a pioneer in Hot Water suits, DUI developed the only active heating technology designed to be used safely underwater.  While many competitors make 12 volt systems, DUI made a system that runs on 6 volts DC within the suit.  The combination of the lower voltage and circuit protection keep the diver safe in the rare case of a suit flood. The variable heat settings allow the diver to control the heat output in order to better control the warmth to duration ratio.
