The made-to-measure Santi Heated Flex 2.0 Undersuit is light and flexible. The Climashield Contour fabric allows for full flexibility in every direction, leading to unique mobility and less bulk when compared with the BZ420X Heated Undersuit.

Santi recommends Flex 2.0 Undersuits to those looking for a thinner alternative for a heating undersuit, plan shorter dives in cold waters or long demanding dives in warmer waters.

The Heated Flex 2.0 Undersuit is designed as part of a complex Santi heating system consisting of items such as BZ420X Heated Undersuitor Heated Vest, Heated Gloves,and SantiBlue Power 9Ah, 14Ah and 28Ah batteries.

The Heated Flex 2.0 contains very efficient heating wires that provide optimal thermal comfort during long and cold dives. Most of the generated heat is passed on directly to the divers body in this configuration.

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 Heated Flex 2.0 Undersuit on top of thin thermal underwear. This configuration directs the temperature straight to a divers body. The Heated Undersuits should not be worn directly on skin due to safety and hygienic reasons.

To operate the Santi Heating system a Santi Drysuit Connector or Thermovalve 303 is required.
