Awearness Kenneth Cole AWEAR-TECH Slim Fit Men’s Suit Separates Coat Dove Gray – Size: 44 Long

Made with AWEAR-TECH 37.5 technology this sport coat features fabric that is triggered by your body temperature to either warm or cool you depending on the situation. The active particles permanently embedded in the yarn capture heat from your body's infrared energy to speed evaporation and cool you if there is moisture vapor (sweat) present or retain that heat to keep you warm when no moisture is present. Suit separates let you choose coat and pant sizes separately for a custom fit.
