Low fabric air permeability. Far Infra-red Manage ratio barrier to avoid breathability vs body heat loss insulation Low conductivity fibres. Keep fabric dry. Spun yarn. Cooling Loose fitting. High fabric air permeability. Reflect sun rays and transmit infrared body heat High conductivity fibres. Filament. Moisture management . Quick drying . Cooling patented technology 6 22/03/2013 THERMAL REGULATION EXPERTISE NECESSITY TO UNDERSTAND INTERACTION BETWEEN BODY AND FABRIC TO QUALIFY (even QUANTIFY) HEAT ECHANGES THAT OCCUR.
