Complimentary “Made to Fit” Service for a Custom Fit
Santi Diving offers a complimentary Made-to-Fit service to ensure your Santi BZ400 Extreme Heated Undersuit fits perfectly. While the standard sizing options suit most divers, you can request up to four size adjustments (2 to 5 cm) on areas such as the chest, arms, waist, hips, legs, and trunk.
For those needing more than four adjustments, Santi also offers the option to add two extra modifications for a nominal fee.
Thermovalve or Drysuit Connector: Which One to Choose?
Both the Santi Thermovalve 303 and the Drysuit Connector are essential for connecting your Santi heated undersuit, vest, or gloves to an external power source. These connectors are available in both Apeks and SiTech fittings.
Santi Drysuit Connector
The Drysuit Connector attaches to your existing drysuit inflation valve, allowing it to continue functioning for inflation while simultaneously powering your heated gear. It adds 19mm of height to your valve.
Santi Thermovalve 303
The Thermovalve 303 offers a unique advantage by positioning the E/O connector cable downward. This feature, along with a 270-degree rotating head, ensures an easy and hassle-free connection of the hopper cable, regardless of the side it is positioned on.
