An original heavyweight sweater-knit fleece, the men’s GORDON LYONS Full-Zip Jacket harkens back to a time when quality meant durability and warmth. This fleece sweater is made of 300 g/m knit fabric for thermal insulation in cool-to-cold conditions. A soft brushed backer seals in the warmth. The exposed reverse coil zipper allows you to regulate your temperature depending on the conditions.
