As fleeces go, the Glacier Pro is a classic. This full-zip jacket version is made from Polartec® micro fleece that delivers lightweight warmth thanks to its unique lofted structure. Air pockets trap air without compromising breathability, so you stay warm without getting sweaty. The chest, shoulders and outer forearms feature a stretch polyester overlay for optimal freedom of movement and improved durability when wearing a backpack. This jacket has two zipped hand pockets, a chest pocket and elasticated cuffs and hem.
