MILITARY & DEFENSE
Thermal performance that disappears under the uniform.
Cold is a readiness problem. It degrades dexterity, attention, and endurance long before it becomes a safety event. HEATJAC™ puts an engineered thermal layer between the body and the cold, under the uniform, without changing anything above it.
HOW THE ARCHITECTURE APPLIES
-
Ultra-low-profile harness construction designed to wear under uniforms and outer layers without altering silhouette or interfering with movement.
-
Contact warming and radiant capture. No fans, no forced air, no noise.
-
The platform is source-agnostic: it accepts long-duration warming elements of the user’s choice rather than depending on one proprietary battery.
-
The patented Thermal Cell Array™ positions warmth where the task demands it: static posts, transport, flight line, or dismounted movement.
-
Dons and doffs in seconds, adjusts across body types, and follows a one-page care guide.
made & developed in america
HEATJAC™ products are manufactured in America, and the platform behind them is protected by two issued U.S. utility patents. Mission-specific configurations are an active part of the HEATJAC development roadmap.
