What Is HEAT-FLOW Fabric?
HEAT-FLOW is an engineered air-fleece fabric system that uses a 3D air-layered structure to retain heat without bulk.
Unlike conventional fleece, which relies solely on thickness, HEAT-FLOW creates a dynamic thermal chamber within the fabric, allowing warmth to circulate while excess heat and moisture escape.
This balance makes HEAT-FLOW suitable for lightweight winter layering, transitional outerwear, and high-comfort daily knits.
In simple terms, it feels warm like fleece, but breathes like knitwear.
Why Choose HEAT-FLOW Fabric?
Air-Layered Warmth You Can Feel
A three-dimensional fleece structure forms millions of micro air pockets that trap heat efficiently without weighing you down.
Breathable Thermal Regulation
The internal air channels allow heat to circulate rather than stagnate, reducing overheating during movement.
Lightweight Yet Insulating
Compared to traditional brushed fleece, HEAT-FLOW delivers comparable warmth with less bulk and improved drape.
Stable Structure & Long-Term Performance
Engineered pile density and knit construction help maintain shape, elasticity, and surface consistency over repeated wear.
HEAT-FLOW Fabric Construction & Technology
3D Air-Layering Structure
A multi-layer knit system creates a self-circulating thermal chamber, locking in warmth while maintaining airflow.
Ultrafine Micro-Pile Fleece
More than 10,000 ultrafine micro-pile fibers per square centimeter create dense yet soft insulation with a smooth hand feel.
Precision Finishing Process
Advanced shearing and finishing techniques ensure consistent pile height, reduced shedding, and improved surface durability.
