Suit separates allow you to choose coat, vest, and pant sizes separately for an ideal fit. Made with AWEAR-TECH 37.5 technology this wool-blend performance vest features fabric that is triggered by your body temperature to either warm or cool itself 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 itself if there is moisture vapor (sweat) present, or retain that heat to keep you warm when no moisture is present. Absorbs odor molecules that are removed when cleaned. Stretch mesh fabric is integrated throughout to ensure maximum mobility and comfort. Pair them with their matching coat and pant (sold separately) for a perfectly coordinated look in just the size you need.
