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)
  • Maximum operating voltage: 12V
  • Sizes: XS (7), S (8), M (8,5), L (9), XL (9,5), XXL (10)


Santi Drysuit Connector is used with your existing drysuit inflation valve.

Once your standard drysuit inflator valve is removed, the Santi Drysuit Connector is placed and secured in the drysuit valve hole. The cables run through the connector. The existing drysuit inflation valve is then screwed on top of the connector. Select Si-Tech or Apeks as the diameter will be different.

E/O cord connector passes through a standard suit inflation valve and provides power connection from the external battery to a heated product under the drysuit.

  • Available with Apeks or Si-Tech thread size
  • Unit hight 19mm + standard drysuit inflator
  • Total length of the cables including 55cm
  • Works with power supply no higher than 12V
