The BLACKHAWK! Engineered-Fit series uses material technology that allows you choose between a body-contoured Standard Fit and full Compression Fit simply by size selection. To achieve a Compression Fit, a true next-to-skin, no movement fit which eliminates potential friction related "hot spots" and helps to reduce muscle fatigue, simply select one size down from your normal size.
