Santi BZ400


Santi BZ 400X, now with new sporty design, is the warmest undersuit we offer. It is designed for diving in water temperature less than 7 degrees Celsius. It is also ideal for long deep diving, with decompression. Experienced divers and instructors helped develop this undersuit. This Undersuit has all the solutions a diver needs! Santi used the best materials and technologies available to produce the BZ400X. Thinsulate BZ 400 insulation is recommended by 3M as optimal for diving undersuits, because it is compressed and do not take too much space under the suit. It also has a net layer, which make the undersuit even more durable and practically indestructible. The lining is made of soft micropolar 190 gr. The outside layer is made of 6.6 Polyamide, 100% additionally reinforced with polyester fabric in the areas exposed to damage. In this model Santi used all the great solutions from the previous version, such as elastic gussets in arms and waist, wide ankle bands and water-resistant cuffs with tapes, which supply air to the dry gloves.
