Small details make a big difference to staying warm. The men's Snorkel fleece is well appointed with the right details to keep you warm on the coldest winter days. Thumb loops add crucial hand-to-wrist coverage, and the quarter-zip snorkel neck seals critical gaps around your neck. The high-loft fleece features an engineered weave proven to help regulate your core temp and limit overheating and sweat build-up. The power of Polygiene® odor control keeps the Snorkel smelling better for longer between washes.
