A warm and flexible base or mid layer, the 5.11 Tactical Sub-Z Quarter-Zip Pullover is crafted from a high-performance blend of 90% polyester and 10% spandex fabric that wicks away moisture to keep you dry and is antimicrobial-treated to reduce odors. The fabric’s interior face is textured for added heat retention, and its compressed fit helps eliminate bunching and rolling. Ergonomically placed flatlock seams reduce chafing for increased comfort when carrying equipment, and the extended length ensures that the pullover will remain securely tucked in at all times. The front zipper extends to the mid-sternum, allowing you to easily adjust your core temperature. Imported.
