Description
SANTI Heated Undersuit Flex 2.0 is designed as part of the complex SANTI Heating System, which consists of such items as a heated undersuit or heated vest, SANTI Thermovalve or SANTI Connector, and an external battery. This configuration allows a diver to use the heating system without any dangers of using an internal battery.
The latest product of SANTI, being part of the Heating System, SANTI Heated Undersuit Flex 2.0, with the same inner heating technology as in the BZ400 heated model, is light and flexible, which increases diver comfort under a drysuit. Made of high-quality 180g/m2 Flex fabric with additional insulation of the chest with a double layer of insulation, it provides full flexibility of the material on every level, which translates into exceptional mobility and smaller volume compared to our model made of Thinsulate insulation. The undersuit 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 directly to the diver’s body. We highly recommend this undersuit to those who look for a thinner alternative for a heating undersuit, plan shorter dives in cold waters, or long demanding dives in warmer waters.
It is advised to wear the undersuit on top of thin thermal or wool base underwear. The lighter version of the undersuit, thanks to new, non-quilted fabric quality, provides more warmth towards the body. This generates better thermal feeling and causes heat retention on the body for longer. The undersuit should not be worn directly on naked skin due to safety and hygienic reasons.
