Santi BZ 400 Heated Undersuit

The Santi BZ 400 Heated Undersuit, A new generation of the Heated SANTI undersuit gives you the best thermal protection under water. It keeps you warm and comfortable while heating even when the batteries are low or completely drained.

And new generation of heating wire covered with ultra-soft, silicone isolation resistant to breaking. Innovative, synthetic power cable resistant to high temperatures and cuts.

The SANTI innovative Heating undersuit is designed as a part of the complex heating system consisting of at least an undersuit, thermovalve/connector and an external battery canister. This configuration allows a diver to  wear the undersuit  under  the  drysuit  without  additional  valve  and  dangers  associated  with  internal  batteries. 

The  heating undersuit outer shell is made of abrasion and tear resistant polyester inside, the Thinsulate™ 3M BZ 400 layer and micro fleece layer inside. The Heating undersuit is designed to be worn over thin form fitting thermal wear.

It is not recommended to wear on in the naked body. In this configuration the majority of the heat output is transferred directly on diver’s torso, back and thighs. The breathable fabric allows the undersuit to heat and keep the warmth of your body and vapor the sweat, if any. The undersuit keeps you warm even when the batteries are low or completely
drained.
