Santi Heated Flex 2.0 Undersuit Combo

The comprehensive Santi Heated Flex 2.0 Undersuit Combo package provides a complete, ready-to-go heating solution for serious divers. This set includes the flexible Heated Flex 2.0 Undersuit, a powerful Blue Power 28Ah Battery, and a Thermovalve 303 or Drysuit Connector. 

Combo Set Highlights

• Advanced Climashield Contour fabric ensures full mobility and reduces bulk.
• Efficient heating wires deliver optimal warmth directly to the diver's body.
• Santi Blue Power Battery offers approximately three hours of consistent run-time.
• Safety features include an integrated switch to prevent overheating during use.
• Field-replaceable battery cable allows for easy maintenance without sending the unit for service.

Santi Heated Flex 2.0 Undersuit

The Santi Heated Flex 2.0 Undersuit remains incredibly light while offering maximum flexibility in every direction. Because it utilises Climashield Contour 180g/m2 insulation, you experience greater mobility than with the heavier Heated BZ420X Undersuit. Furthermore, the non-quilted fabric traps heat closer to your skin for longer. This design ensures that most generated heat passes directly to your body for thermal comfort.

For safety and hygiene, you should wear this undersuit over thin thermal underwear rather than directly on your skin. This configuration directs the 110W maximum heating power effectively while protecting your body. Additionally, the suit features built-in heating glove wires and a handy waist pocket for the power cord. 

Technical Specifications

• Maximum heating temperature: 45ºC
• Heating power: 110W for intense thermal protection.
• Durability: Wires feature ultra-soft, break-resistant silicone covers.
• Convenience: Includes a P-valve opening and elastic gussets for comfort.
• Fit: Available in stock male and female sizes.

Santi Blue Power Battery 28Ah

The Santi Blue Power Battery 28Ah introduces a new generation of reliable power for your heating system. This battery allows you to maintain a constant heating temperature throughout your entire dive for up to 3 hours. 

This battery distinguishes itself by maintaining a stable voltage level regardless of the remaining charge. You can choose between two output levels: 11V for standard warmth or 12V for higher heating needs. 

Moreover, the piezoelectric button ensures failure-free operation even in the most demanding underwater environments. Furthermore, the ergonomic anti-slip casing makes it very easy to handle while on the surface. Finally, the audible and luminous indicators clearly indicate your battery mode and low-charge levels. < Click for Full Description >

Drysuit Connector vs. Thermovalve 303

The Santi Drysuit Connector links your Santi Heated Vest Flex 2.0 to an external battery via your existing inflation valve. You simply install the connector underneath your current drysuit inflation valve to maintain full inflation functionality. < Click for Full Description >

In contrast, the Santi Thermovalve 303 fully replaces your existing inflator valve with a streamlined, dual-function unit. The Thermovalve features a 270-degree rotating head to improve hose routing and flexibility. Consequently, you can customise your setup to suit your specific diving preferences. < Click for Full Description >

FREE "Made to Fit"

Very few divers require a totally made to measure suit due to the wide range of standard sizes available from Santi Diving. With this in mind, Santi offers a free of charge Made-to-Fit service to any standard size Heated Flex 2.0 Undersuit ordered, sculpting standard suits to a divers' measurements.

With your order, you can request up to 4 changes (ranging from 2 to 5 cm) to any of the standard size measurements listed under chest, inner arm, biceps, forearm, waist, hips, inner leg, thigh, calf or body trunk on the Santi size chart.

If you would require more than 4 changes to make your suit perfect, you can add two more changes for a small additional charge.
