SANTI Heated Flex 2.0

Flexible lightweight solution to underwater heating

The Santi Flex 2.0 Heated Undersuit is a light and flexible solution to underwater heating systems where mobility and flexibility matters.

The Climashield Contour fabric allows for full flexibility of fabric in all direction, which leads to unique mobility and less bulk when compared with BZ400 Heated Undersuit.

Due to its properties the SANTI FLEX 2.0 is ideal for dives in cold waters that don’t involve extensive runtimes or long demanding dives in warmer waters – while offering a lighter alternative to current BZ400/Heating system owners.

The Flex 2.0 Heated Undersuit is designed as part of complex Santi heating system which consists of such items as BZ400 Heated Undersuit or Heated Vest, Heated Gloves, SANTI Drysuit Connector, SANTI Thermovalve 303, 6Ah Battery and 24Ah Battery.

The Flex 2.0 contains very efficient heating wires that provide optimal thermal comfort during long and cold dives. In this configuration, most of the generated heat is passed on directly to the diver?s body.?

Thanks to new, non-quilted fabric quality, the Flex 2.0 provides more warmth towards the body. This generates better thermal properties and keeps the heat trapped closer to the body for longer. It is advised to wear the Santi Flex 2.0 on top of thin thermal underwear. In this configuration the temperature is directed straight to a diver?s body.

The undersuit should not be worn directly on skin due to safety and hygienic reasons.
