Heated SANTI undersuit Extreme BZ400 is designed as a part of the complex heating system consisting of the undersuit, thermovalve/connector and an external battery canister.

This configuration allows a diver to wear the gloves under the dry gloves without additional valve and dangers associated with internal batteries.
The outside layer is made of durable Polyester, Thinsulate™ 3M BZ400 inner insulation and soft Polar lining. The undersuit is designed to be worn on thermal underwear. In this configuration most of the generated heat is transferred directly to the diver’s body.

Breathable Thinsulate™ Insulation gives you the best thermal protection and takes sweat away from your body. It keeps you warm and comfortable while heating even when the batteries are low or completely drained.
