The Carhartt Base Force Heavyweight Poly-Wool Quarter-Zip is a cold-weather base layer built on a 6.5-ounce face of 81% polyester and 19% wool, backed with a polyester-cotton knit. Wool regulates temperature and resists odor, while FastDry moves sweat off the skin and Rugged Flex adds stretch for bending and reaching. A mock-neck collar with a quarter zip, a zippered chest pocket and thumb loops make it a working layer rather than a plain thermal. It suits people who work or spend long hours outdoors in the cold and want one layer that handles sweat and smell; against pure synthetic thermals it adds wool's warmth-to-weight and odor control, and against all-wool base layers it is cheaper-feeling, less breathable and more prone to pilling. Buyers rate it well overall, with fit and warmth drawing the most praise and sizing running large for some.
