Santi BZ420x Heated Undersuit Lady

Santi BZ420x Heated Undersuit Lady stands out with a warmer build and a more uniform heating layout for demanding drysuit dives. This heated undersuit is designed to be worn under a drysuit to boost thermal insulation while still allowing natural movement. A smoother inner surface and updated quilting help it slide on and off more easily and sit closer to the body. It is intended to be used as part of a system with SANTI Thermovalve or SANTI Connector and an external battery to avoid placing batteries inside the suit.
