Santi BZ420X Ladies First

SANTI BZ420X Ladies First undersuit for cold-water drysuit diving

SANTI BZ420X Ladies First is a very warm women's technical undersuit for divers who need reliable insulation under a drysuit in demanding cold-water conditions. It follows the BZ420X concept, the warmer evolution of the well-known BZ400X, and adapts it to the Ladies First fit.

The undersuit is made for long dives, decompression dives and intensive drysuit diving in low water temperatures. It combines Thinsulate BZ400 by 3M, Thermo Pile and contrast materials to deliver high thermal comfort while preserving mobility for valve operation, finning and equipment handling.
