HEATJAC CORE™
The Foundational Thermal Performance Platform
HEATJAC CORE™ is the flagship wearable thermal management platform from HEATJAC, designed to help users remain comfortable, focused, and effective in demanding environments.
Originally developed by a physician to address thermal comfort challenges experienced by healthcare professionals working in cold operating rooms, HEATJAC CORE™ was created from a clinical understanding of how environmental conditions can affect comfort, concentration, and performance during long hours on the job.
Its patented wearable architecture provides a versatile foundation for multiple thermal management configurations without sacrificing mobility, fit, or comfort. Lightweight, low-profile, and designed for extended wear, HEATJAC CORE™ can be worn discreetly beneath scrubs, uniforms, workwear, tactical gear, or outdoor apparel.
Today, HEATJAC CORE™ is trusted across healthcare, industrial, commercial, outdoor, and recreational environments where maintaining comfort can directly impact performance, productivity, and endurance.
For applications requiring additional thermal support, HEATJAC CORE™ is compatible with optional heating and cooling accessories, allowing users to adapt to changing environmental conditions and personal comfort preferences while maintaining the same streamlined wearable platform.
