It offers unparalleled thermal comfort even in extreme conditions thanks to construction improvements and new materials.

The heated BZ420X undersuit is designed to comprehensively protect the whole body of a diver from the cold. The heated undersuit heats the trunk, thighs and arms evenly.

It is designed to be worn on top of a thin base _, allowing most of the generated heat to be passed directly to the diver’s body.

The heated Santi undersuit gives you the best thermal protection underwater. It keeps you warm and comfortable while heating, even when the batteries are low or completely drained.

What’s new in the BZ420X Heated Undersuit?

A high-quality and thicker inner _ provides superior thermal insulation, making it warmer than BZ400 Extreme.

The new cable layout ensures more even heat distribution and more efficient heating.

A new, smooth inner material makes donning and doffing easier. The “brick” pattern of the improved quilting enhances flexibility and body fit.
