The Heavyweight Baselayer Top is your first layer of defense in extreme cold. Built for hunters who sit still through brutal wind, early dark, and late opportunity, it traps critical heat while managing moisture and odor with the natural power of merino wool. The full-zip design allows for quick ventilation, and the integrated hood adds warmth and concealment without extra layers. It’s the baselayer that keeps you warm without fail—and quiet without compromise—so you can stay locked in when everything else tells you to quit.
