Heated Undersuit Flex 2.0 by Santi
SANTI Heated Undersuit Flex 2.0: Warmth Without the Restriction
Cold water diving usually demands thick, bulky layers that make you feel like a stiff mannequin. The SANTI Heated Undersuit Flex 2.0 solves this problem by delivering active warmth in a lightweight, flexible package. Designed as a thinner alternative to the heavy BZ400 heated model, this undersuit is perfect for divers who want to maintain full range of motion while extending their bottom time in cold water.
Advanced Heating Technology
SANTI designed this suit to keep heat exactly where you need it—close to your body. The new, non-quilted fabric construction traps generated heat effectively, creating a better thermal experience than previous models. Inside, ultra-soft heating wires covered in breakage-resistant silicone distribute 110 Watts of power. This system generates a maximum temperature of 45°C (113°F), ensuring you stay comfortable even during long decompression stops.
Mobility and Comfort
The suit utilizes Climashield Contour fabric (180g/m2), a material chosen specifically for its ability to stretch in every direction. This gives you full flexibility to reach valves, check gauges, and swim efficiently without fighting your gear. Elastic gussets under the armpits and an elastic waist belt further enhance the fit, removing bulk so your drysuit fits better.
Safety and Control
You stay in control of your thermal profile. A thermal safety switch, stowed in a handy waist pocket, protects against overheating and current surges. The suit is also designed for practical diver needs, featuring a dedicated p-valve hose opening, water-resistant cuffs with thumb loops, and foot straps to keep everything in place while dressing.
System Requirements
This undersuit acts as the core of your heating system. To function, it connects to an external battery canister via a SANTI Thermovalve or Connector (sold separately). This external battery setup eliminates the risks associated with internal battery canisters and avoids the need for extra drysuit inflation valves.
Important Usage Advice: For maximum efficiency and safety, wear this undersuit over a thin thermal or wool base layer. Do not wear it directly against naked skin.
