Lightweight mid-layer for mountain trekking where weight is important. Quick-drying and insulating, this close-fit layer is good for spring, summer, fall and mild weather. The product has very good breathability and the stretch fabric gives effective moisture transportation. Also the extra long neck-to-chest-zip aids venting. A favorite for both running and hiking. We’ve also integrated silver content to prevent odor.
