HeatLock® is a proprietary thermal insulation technology engineered to reduce heat loss while preserving comfort, mobility, and design integrity.
Built at the fiber level using advanced materials and precision engineering, HeatLock® delivers lightweight, efficient warmth without bulk, stiffness, or visual compromise.
Thermal performance, built into the fiber
Staying warm shouldn’t mean sacrificing comfort, movement, or design.
HeatLock® uses a proprietary material system that combines low thermal conductivity materials with air-retentive architectures to slow heat transfer away from the body.
Instead of relying on thick insulation sheets or rigid foams, HeatLock® distributes its thermal function across millions of individual fibers. Each filament independently traps air and reduces heat loss, creating billions of micro air pockets throughout the textile structure.
The result: consistent warmth, lighter weight, and better garment performance, even in compressed or layered applications.
APPLICATIONS
HeatLock® is designed to be adaptable across product categories and environments.
Base layers and thermal garments
Padding, flock, and structured textiles
Workwear, protective gear, and lifestyle apparel
Traditional Insulation
Thickness-dependent warmth
Added bulk and stiffness
Performance loss over time
HEATLOCK® VARIATIONS
Ultra-light thermal performance
HeatLock® AERO integrates a proprietary patent pending aerogel system, the lightest solid material known, into a fiber-level insulation architecture. This allows exceptional thermal resistance at minimal weight while preserving softness, stretch, and garment movement.
Best for:
Key characteristics:
Thermal retention with moisture balance
HeatLock® WAVE combines heat retention with enhanced moisture management, helping maintain a stable microclimate during activity. The structure supports warmth while allowing sweat to move away from the body, reducing chill during transitions.
Best for:
Key characteristics:
Maximum insulation efficiency, reduced weight
HeatLock® HOLLOW uses hollow-core filament construction to trap insulating air within each fiber while integrating proprietary insulative elements in the sheath. This dual barrier approach reduces heat transfer while lowering overall material weight by up to 30%.

Key characteristics:
A proprietary thermal insulation technology engineered to reduce heat loss without bulk, stiffness, or design compromise, delivering lightweight, efficient warmth at the fiber level.
HeatLock® is engineered at the fiber scale, meaning thermal performance is intrinsic to the material itself, not applied as a coating or finish. This allows warmth to remain consistent through wear, movement, and compression.
By trapping air within carefully engineered microstructures, HeatLock® reduces conductive and convective heat loss — the two primary pathways through which body heat escapes.
HeatLock® increases thermal performance through fiber layering rather than bulk. As fibers are layered, thermal efficiency improves without adding stiffness or excessive loft.
Unlike foam-based padding systems, HeatLock® maintains softness, drape, and flexibility, allowing garments to move naturally with the body.
