The cousin of the iconic Double Thick Pullover sweatshirt, Arborwear's Double Thick 1/2-Zip Sweatshirt is a slightly lighter, yet still very thick and warm, version of the original with no hood and the addition of a half-zip opening at the front. While most "heavyweight" sweatshirts use a 10-13oz. fabric, this beast of a fleece features two layers of 12oz. cotton to keep you warm when you're working in harsh conditions. Gusseted armpits offer greater mobility when you're chopping down trees or framing a house, and the half-zip opening allows you to vent excess heat when you start working up a sweat.
