The undersuit is designed to be worn on top of a thin base layer allowing most of the generated heat to be passed directly to the diver’s body.

The Heated SANTI undersuit gives you the best thermal protection under water. It keeps you warm and comfortable while heating even when the batteries are low or completely drained.

DOWN MANUAL: Santi Heating System Manual


Santi Heated Gloves are very soft, and do not hinder the movements in any way. The thin heating cables are arranged and sewn in such a way that they are practically imperceptible. Under your dry glove you don’t feel the difference – is it your normal gloves or the heated ones? But you can feel the difference in the comfort you experience.

Hands are the first to get cold. When chilled and numb they cause discomfort. But they are also incapable of proper handling of inflator or valves, taking pictures or filmmaking. Capable hands are also helpful if you want to quickly escape troubles underwater.

Evenly distributed heating wiring that allows for freedom of movements in palms. The gloves keep your hands warm even when the heating is not on.

Gloves can be easily connected to Santi Heated Vest or Undersuits without any additional cables.

  • Includes: gloves and cables
  • Breathable fabric
  • Maximum heating temperature 45°C
  • Maximum heating power: 36W (pair)

The Santi Thermovalve 303 completely replaces your exsisting drysuit inflation valve.

Unlike the Santi Drysuit Connector, it offers two functions in one device: drysuit inflation valve with an integrated connector for Santi heating systems. Select Si-Tech or Apeks as the diameter will be different.

Its great advantage is placing the cable with the E/O connector in the down position, with the possibility of turning the head by 270 degrees, which allows for trouble-free connection of the hopper cable both in the position of the connector to the right and left.

  • Includes E/O Blind Plug
  • Available with Apeks or Si-Tech thread size
  • Unit hight 29mm
  • Total length of the cables 55cm
  • Works with power supply no higher than 12V
