SANTI Heated Undersuit Flex 2.0 is designed as part of the complex SANTI Heating System and consists of the heated undersuit or heated vest, SANTI Thermovalve or SANTI connector and external battery. The Flex 2.0 offers the same inner heating technology as the BZ400 and is light and flexible, which increases diver's comfort under a drysuit.  Made of high quality 180g / m2 Flex fabric with additional insulation of the chest with a double layer of insulation, 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 on directly on the diver's body.  We highly recommend this undersuit to those who look for thinner alternative for a heated undersuit, plan shorter dives in cold waters or long demanding dives in warmer waters. It is advisable to wear the undersuit on top of thin thermal or wool base underwear. 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.
