The SANTI BZ400 Heated Undersuit is the ultimate solution for divers seeking maximum warmth and comfort during extended cold-water dives. Combining the exceptional insulation of Thinsulate™ BZ400 with an integrated heating system, this premium undersuit delivers outstanding thermal protection even in the most demanding conditions.

Designed as part of the complete SANTI Heating System, the BZ400 Heated Undersuit works in conjunction with a SANTI Thermovalve or Connector and an external battery, providing safe, reliable heating without the risks associated with internal battery systems.

Constructed with a durable, abrasion-resistant outer shell and insulated with 420 g/m² Thinsulate™ BZ400, the undersuit provides exceptional warmth even when the heating system is switched off. The breathable materials efficiently transfer moisture away from the body while the integrated heating elements deliver warmth directly to the torso, back, thighs, and arms for superior comfort throughout your dive.

For best performance, the undersuit should be worn over a lightweight thermal base layer and not directly against bare skin.
