The Snorkel fleece is a must have performance baselayer on the coldest winter days. Thumb loops keep your hands covered and the wind-stopping quarter-zip snorkel collar enhanced with Polygiene odor control technology fights off odor-causing bacteria so your fleece stays fresh longer. The high loft stretch fleece fabric is woven with a unique NanoRed polyester, engineered to regulate body heat, which improves blood circulation and helps prevent fatigue. Flat locked seams and under arm gussets give you a comfortable fit and range of motion under layers.
