HEATJAC™ was founded on a simple observation: when professionals are uncomfortable, performance can suffer.

After years working in healthcare environments, physician and anesthesiologist Dr. Mark Silverberg, DDS, MD experienced firsthand the challenges created by cold operating rooms and temperature-controlled clinical settings. While these environments are essential for patient care and procedural requirements, they often leave healthcare professionals working for hours in conditions that can be physically uncomfortable and mentally distracting.

Rather than accepting the problem as unavoidable, Dr. Silverberg set out to create a better solution.

The result was HEATJAC™—a company dedicated to developing innovative wearable thermal management solutions that help people remain comfortable, focused, and effective in demanding environments.

From Healthcare to Everywhere Performance Matters

What began as a solution for healthcare professionals quickly revealed a broader opportunity.

The same challenges experienced by clinicians in operating rooms and procedure suites are shared by countless professionals and enthusiasts working or spending time in temperature-controlled, cold-weather, or demanding environments. Industrial workers, utility personnel, outdoor professionals, motorcyclists, recreational users, and others often face the same need for thermal comfort without sacrificing mobility or performance.

Today, HEATJAC products are used across healthcare, industrial, commercial, outdoor, motorsports, and recreational applications, helping users stay focused on the task at hand rather than the temperature around them.

A Different Approach to Thermal Management

HEATJAC products are designed around a simple philosophy: thermal comfort solutions should work with the user—not against them.

Rather than relying on bulky layers, restrictive garments, or one-size-fits-all approaches, HEATJAC develops lightweight wearable platforms that integrate seamlessly into existing apparel, uniforms, workwear, and professional environments.

This philosophy has led to a growing portfolio of thermal management solutions designed to support a wide range of user needs, environments, and performance requirements. From physician-designed wearable systems to adaptable heating and cooling solutions, every HEATJAC product is developed with a focus on comfort, practicality, and real-world usability.

Designed for Real Life

Innovation only matters if it works in the real world.

Every HEATJAC product is created with a focus on durability, simplicity, and everyday functionality. Whether worn beneath scrubs in a healthcare setting, integrated into industrial workwear, layered under outdoor apparel, or used during recreational activities, HEATJAC solutions are designed to fit naturally into the user's environment and routine.

The goal is not simply to provide warmth or cooling. The goal is to help people remain comfortable, confident, and capable when performance matters most.
