The Duck Camp Barnburner 1/4-Zip Top is a heavyweight sweater that regulates our temperature and moisture well thanks to its merino wool construction. Merino wool is naturally odor-resistant, insulates when wet, and dries quickly, making it a great material for cold and changing temperatures. The quarter-zip also lets us ventilate and dress quickly, while the hidden thumbholes let us layer over this sweater without the sleeves riding up.
