Fonctionnement

AeroFIR™ integrates three complementary materials into a unified performance system. Aerogel polyester — derived from NASA aerospace insulation technology — traps heat within its nano-porous structure, blocking thermal loss even in sub-zero environments. Far-infrared emitting polyester absorbs body heat and re-emits it as far-infrared energy in the 8–14 μm wavelength range, helping maintain a warm and comfortable microclimate around the foot. Wool completes the system by actively managing moisture during high-intensity activity and maintaining insulation even when damp. Together, these three materials create a self-regulating warmth and comfort system that no single fiber can achieve alone.

Triple-Layer Thermal System

AeroFIR™ combines aerogel’s passive insulation (thermal conductivity as low as 0.017 W/m·K) with far-infrared active warming and wool’s natural wet-weather insulation — delivering consistent thermal comfort across a wide range of activity levels and environmental conditions.

Far-Infrared Comfort & Wellness Positioning

The FIR polyester component emits far-infrared energy that supports warmth retention and a comfortable sensation during prolonged wear. Widely used in wellness and comfort-oriented textile applications, FIR technology is a recognized positioning advantage in premium performance and recovery-inspired apparel markets.

Applications

AeroFIR™ is purpose-built for performance environments where warmth, comfort, and durability must work together. Its elite thermal insulation and active warming properties make it the ideal yarn for high-performance hiking socks, ski and snowboard socks, and cold-weather trail running socks — where maintaining foot warmth inside stiff boots or across unpredictable terrain is critical. The lightweight construction and moisture-balancing wool component further support long-distance endurance applications.

Beyond outdoor sports, AeroFIR™’s far-infrared warming and comfort positioning make it well-suited for long-haul travel socks, wellness-oriented lifestyle socks, and premium everyday thermal socks. Its multi-functional material system also opens opportunities in health and wellness product categories, where warmth retention and comfort-focused FIR technology are valued by consumers seeking functional, recovery-inspired textile solutions.
