HEATED UNDERGARMENT SYSTEM

Engineered for performance and comfort, KWARK's Heated Undergarment System is crafted with proven NAVY fabric and tested for durability, flexibility, and thermal efficiency. Designed to layer effortlessly under any dry suit without compromising mobility, the undergarments feature modular heating panels that work independently and deliver consistent warmth.

Intelligent Heat,
Modular Design

The core of the system is the Kwark Heated Undergarment, a flexible, ergonomic suit designed to layer effortlessly under any drysuit. It features ten independent heating panels, delivering 80W of total power, strategically distributed across the torso, limbs, and extremities for full-body warmth. Even if a single panel fails, the others continue to operate seamlessly — and any damaged module can be easily replaced without removing or repairing the entire garment.

Complete Compatibility

Kwark’s system is fully modular. Each component — heated undergarment, vest, gloves, and socks — integrates effortlessly with one another, ensuring a personalized heating setup tailored to the dive and diver.

Performance You Can Rely On,
Comfort You’ll Feel

Built on the battle-tested NAVY EXTREME foundation, Kwark’s Heated Undergarment System is engineered for professional-grade thermal performance in the harshest diving conditions. Whether you're pushing the limits of depth or duration, this system delivers consistent heat — and remains thermally protective even in complete submersion or power loss.

Precision Power, Trusted Safety

Powered by external 12V batteries, Kwark's system eliminates the risks associated with internal batteries. A safety fuse and thermal switch ensure maximum temperatures do not exceed 45°C, protecting the diver and the gear.
REQUIRES - a thermo valve and external battery - supplied separately.
