The Santi BZ400X Ladies First Undersuit is one of the warmest on the market today for it's size. Made for diving in waters below 7°C the BZ400X is ideal for the demanding diver that needs warmth without bulk that has been tried and tested by industry leaders.


Warm Without Bulk

The internal lining is a soft 140g/m2 micropolar fleece that is comfortable against your skin or your base layer. The outer shell is made from 6.6 Polyamide that has polyester reinforcing in key areas for durability. These two layers surround the internal Thinsulate™ that is quilted to prevent cold patches forming by holding all layers together.

Together weighing 420g/m2 and a warmth rating of 1.8clo the BZ400X is incredibly warm for the cold water diver.



Elasticated gussets under the arm and around the waist allow full range of movement without restriction for whatever you need to do in the water.

Prefabricated holes through the suit are located to integrate heating cables for gloves and vests in the chest and a P-Valve down the thigh.

Suspenders, thumb loops and a wide elastic stirrup strap combined with the anatomic shape of the suit hold the suit in the correct position in the water without riding up in any areas.


Ladies First

Santi know that female divers are a different shape and have different needs to male divers so they introduce the female specific BZ400X with a feminine shape, detailing and features.

The seat section of the undersuit can be unzipped so you don't have to take the entire undersuit off when you need to go to the bathroom.


3 pockets including inside pocket,
water-resistant cuffs,
tapes, which supply air to the dry gloves,
yoke and collar covered with softshell,
two-way zip,
back of the undersuit opened with round zipper,
reinforcing patches on knees and arms,
