The Sitka Traverse Zip-T is an abrasion-resistant outer layer for mild days and an insulating mid layer for the cold. The durable knit outer face fabric protects a soft fleece backer that traps warm air to distance your skin from the elements. The half zip pullover construction with zippered chest pocket delivers a tailored fit. Sleeves break below the wrist with integrated thumb loops to keeping the shirt in place from ravine to ridge top.
