Joseph Abboud Cadman Commuter Moc Toe Slip On Loafers Black/White Sharkskin

Made with AWEAR-TECH 37.5 technology, this vest 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.
