BLACKHAWK! Products Group presents the Warrior Wear Thermostatic Base-Layer garments Engineered Fit series. These garments are designed to regulate body temperature, wick out moisture, inhibit and control the growth of odor causing bacteria and allow freedom of movement with maximum comfort. Material technology lets wearers choose between a body-contoured Standard Fit and a full Compression Fit. The Compression Fit eliminates any potential friction related "hotspots" and helps to reduce muscle fatigue. The garments have a smooth matte-finish to reduce bulk when layering. Stretch mesh panels enhance the freedom of movement and help to dissipate body heat. Flat-seam construction and a seamless top-of-shoulder construction prevent irritation.
