Southern Marsh crafted the Copper Trail Fleece Pullover out of an extremely soft polyester fleece fabric that brings much more to the table than a standard cotton fabric. The polyester fleece is lightweight, yet incredibly warm thanks in part to the nature of the fabric. Polyester fleece also helps control moisture while retaining heat, making this pullover ideal as a layering piece wherever you take it. The front pockets are purposefully positioned to be in an ideal location for storing your wallet, keys, phone or just for keeping your hands warm. Since this pullover is lightweight, Southern Marsh choose to line it with the same ultra soft polyester fleece they made it out of which really helps insulate you in the cold. That being said, if you are going to be outside and active in the cold, this is the perfect pullover for you.
