Santi BZ420x Women's Heated Undergarment: Unmatched Thermal Protection for Cold Dives

The Santi BZ420x heated undersuit is an evolution of Santi's flagship undergarment, specifically designed to provide exceptional thermal protection for women diving in demanding, cold-water environments. This isn't just insulation; it's active heating to keep you warmer during longer dives.

What makes the BZ420X stand out?

  • Enhanced Warmth: Features a high-quality, thicker inner layer (290 g/m²) for superior thermal insulation, even without the heating activated.
  • Improved Heat Distribution: A new heating cable layout ensures heat is spread more evenly across your torso, thighs, and arms.
  • Effortless Donning: A new, smooth inner material makes slipping into the undersuit much easier.
  • Better Fit & Flexibility: An updated "brick" quilting pattern enhances body fit and allows for greater freedom of movement.

This undersuit is part of Santi's heating system and requires a Santi Thermovalve or Santi Connector and an external battery pack (sold separately) to function. This configuration keeps the battery outside your drysuit for operational safety.

The heating system delivers a maximum temperature of 45°C (113°F) with a maximum power output of 110W. It includes temperature and overcurrent protection. Wiring is ergonomically placed, and extra cables in the sleeves allow for easy connection to heated gloves (sold separately).

Other practical features include an elastic waistband, P-valve holes on both sides, two side pockets, an extra pocket for power cables, water-resistant cuffs, and straps at the cuffs to prevent riding up and allow air release. A two-way zipper provides added ease of use.
