The SANTI BZ420X Heated is a professional heated drysuit undersuit designed for cold water, long dives, and extreme conditions. The model is an enhanced version of the flagship BZ420X undersuit and combines high thermal insulation with an effective active heating system.
The main advantage of the BZ420X Heated is maximum thermal comfort even in demanding conditions. The undersuit retains heat on its own, while the integrated heating elements provide additional warmth to the torso, thighs, and arms. Thanks to the new cable layout, heat is distributed more evenly, while the ergonomic wiring does not restrict movement under the drysuit.
The updated inner layer is warmer and more comfortable against the body, while the smooth material makes the undersuit easier to put on and take off. The improved brick-pattern quilting increases flexibility, helps the undersuit fit the body more comfortably, and allows it to retain its shape during regular use.
The BZ420X Heated is part of the complete SANTI heating system and operates with an external battery through a SANTI Thermovalve or SANTI Connector. This solution allows the heating system to be used under a drysuit without internal batteries, making it safer and more convenient for long dives.
The undersuit features a two-way zip, side pockets, an additional cable pocket, an elastic waist panel, water-resistant cuffs, P-valve openings on both sides, and additional cables in the sleeves for connecting heated gloves.
The SANTI BZ420X Heated is the choice for divers who need maximum thermal protection, active heating, and comfort during cold-water diving, technical diving, and long decompression dives.

The SANTI Heated Undersuit Flex 2.0 is an actively heated drysuit undersuit designed for cold water, long dives, and situations where the diver needs to maintain stable thermal comfort underwater. The model is part of the complete SANTI heating system and works with an external battery, SANTI Thermovalve, or SANTI Connector.
The main advantage of the Heated Undersuit Flex 2.0 is its combination of active heating, freedom of movement, and safety. The heating elements are evenly distributed across the torso, thighs, and arms, so warmth is provided throughout the main areas of the body rather than in isolated zones. The wiring is positioned so that it does not restrict movement or interfere with equipment handling.
The system connects to an external battery and does not use an internal battery inside the drysuit. This solution makes the heating system safer and more convenient for long dives. The undersuit also retains heat when the heating is switched off, so it can be used as a complete warm insulating layer under a drysuit.
The Heated Undersuit Flex 2.0 features a two-way zip, two side pockets, an additional cable pocket, water-resistant cuffs, an elastic waist panel, and P-valve openings on both sides. The standard configuration includes additional cables for connecting heated gloves, as well as air channels for dry gloves.

The SANTI Heating Vest Flex 2.0 is an actively heated drysuit vest designed for divers who need additional thermal protection without using a fully heated undersuit. The model is part of the complete SANTI heating system and works with an external battery, SANTI Thermovalve, or SANTI Connector.
The main advantage of the Heating Vest Flex 2.0 is the ability to increase thermal protection specifically where it is most important: around the torso. The vest can be used as an additional layer under a drysuit in cold water, during long dives, decompression, or in situations where the main undersuit does not provide enough warmth.
The heating elements provide comfortable active heating, while the new generation of heating wires with soft silicone insulation makes the vest more reliable and resistant to damage. The internal wiring is arranged ergonomically, so the vest does not restrict movement and remains comfortable under an undersuit and drysuit.
The Heating Vest Flex 2.0 connects to an external battery and does not use an internal battery inside the drysuit. This configuration improves system safety and allows the operating time to be selected according to the specific dive: approximately 1 hour with a 9Ah battery, 3 hours with a 14Ah BluePower battery, and 6 hours with a 28Ah BluePower battery.
The vest features a water-resistant connector compatible with other SANTI products, a concealed power cable in a convenient pocket, side and crotch adjustments for a better fit in length and volume, and an opening for a P-valve hose. A special storage and transport bag is included.

The SANTI 303 Thermovalve is a drysuit inflation valve with an integrated 12V connector, designed to safely connect the SANTI heating system to an external battery. It is a key component of the complete heating system, allowing a heated undersuit, vest, or gloves to be used without placing the battery inside the drysuit.
The main advantage of the Thermovalve is that it combines the standard drysuit inflation function with a convenient external power connection. The valve is installed on the drysuit in place of a standard inflation valve and performs two functions at the same time: supplying gas to the suit and transmitting power from the external battery to the heating elements.
The rotating valve head allows the inflation hose and E/O cord to be positioned conveniently so that they do not interfere with movement or equipment handling. This is especially important during technical, cold-water, and long-duration dives, where a streamlined equipment configuration directly affects diver comfort and safety.
The Thermovalve connects to an external battery designed for underwater use and is compatible exclusively with the SANTI heating system. This configuration makes the heating system safer and more convenient, as the battery remains outside the drysuit.
The SANTI 303 Thermovalve is an essential component for divers who use the SANTI heating system and need a reliable, streamlined, and safe external power connection for a heated undersuit, vest, or gloves.
Advantages of the SANTI 303 Thermovalve:
