Flexible lightweight vest for thermal comfort

The Santi Heating Vest Flex 2.0 is a 2020 product for those who seek the highest level of comfort with greater flexibility during long and cold dives. Introduced at the Boot Show on 18 January for the first time, the new Flex 2.0 heating vest, has been designed as part of the Santi heating system which currently consists of such items as the Santi heated undersuit and the original robust heated vest, thermo connector or thermovalve and external battery.

SANTI Heated Vest Special OfferThe vest was designed to provide the highest functionality and safety. And like the original vest, thanks to fabrics used, the vest provides thermal comfort even after your battery is drained.

The external layer has also windproof properties. (The original heated vest is made from 200gr Thinsulate for insulation)

SANTI Heating Vest

To operate the Santi Heating Vest Flex 2.0 the following can be purchased separately:

Santi Drysuit ConnectorSanti Drysuit ThermoConnector – Uses existing drysuit inlet valve

Santi Drysuit Connector connects your Santi Heated Vest, Gloves or Undersuit to the battery using your existing drysuit inflation valve (Apeks or SiTech).

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.

  • Works with power supply no higher than 12V
  • Total length of the cables including 55cm
  • Height without the valve – 19 mm
  • Available with “Apeks” or “Si-Tech” srew size
  • CE certified

Once your Sitech or Apeks 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 valve is then screwed on top of the connector. Select which (Sitech or Apeks) valve you currently have under options as the diameter will be different.

Santi ThermovalveSanti Thermovalve – All in one

he Santi Thermovalve connects Santi Heated Vest, Gloves or Undersuit to a external battery. It replaces the standard 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.

The 90º moveable valve head provides convenient hose attachment which allows for optimal E/O cord and pressure hose settlement under the drysuit.

  • Includes E/O Blind Plug
  • Works with power supply no higher than 12V
  • Total length of the cables 55cm
  • Ergonomic design
  • Available with “Apeks” or “Si-Tech” screw size
  • CE certified

Dry suit inflator valves are user replaceable. Your current valve (Apeks or SiTech) will need to be removed. Basically it will have to be screwed out. Once the dry suit valve hole is apparent, it is advisable to clean the area on both sides before installing the new Thermovalve in its place. Screw the valve in and tighten – you’re ready to go!
