HEATJAC CORE™ - LEGACY is the original 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.

The HEATJAC REFLECT™ vest is a lightweight thermal garment engineered to help your body retain warmth without the bulk of traditional insulated apparel. Utilizing HEATJAC's proprietary heat-reflective lining technology, REFLECT™ returns radiant body heat back toward the wearer, helping maintain comfort in cold environments while preserving mobility and freedom of movement.
Designed for healthcare professionals, outdoor enthusiasts, cold-sensitive individuals, and anyone who spends extended periods in challenging temperatures, REFLECT™ delivers practical warmth in a streamlined, low-profile design that layers comfortably beneath uniforms, scrubs, jackets, and everyday clothing.
Integrated warming pockets allow REFLECT™ to be paired with compatible long-duration warming elements (sold separately) for additional thermal support when conditions demand it.
• Lining returns up to 95% of radiant body heat, based on material testing to ASTM C1371.
• Engineered heat-reflective thermal lining: warmth without insulation bulk.
• Lightweight, low-profile, designed for all-day wear.
• Integrated pockets for compatible warming elements.
• Snap-front closure; layers under scrubs, uniforms, workwear, and outerwear.
• Simple care: follow the included care guide (remove warming elements first).)
Operating rooms, imaging suites, emergency departments, and labs are kept cold by design. REFLECT™ helps the people working in them stay warm and comfortable through long shifts, with full mobility and nothing added over the uniform.
Many people managing cold-sensitivity, including those living with Raynaud’s, look for simple, reliable ways to stay warm. REFLECT™ is designed to help reduce overall heat loss by reflecting body heat back toward the wearer, supporting core warmth without heavy layers, in cold offices, hospitals, air-conditioned spaces, and winter conditions.
REFLECT™ is a comfort product, not a medical device, and is not intended to diagnose, treat, cure, or prevent any disease or condition.
