Klim Mesa Falls Wool Long Sleeve Shirt

The KLIM Mesa Falls Wool Long Sleeve Shirt is a lightweight performance layer built for year-round comfort and versatility. Constructed from a premium merino wool and nylon jersey blend, it combines natural temperature regulation, odor resistance, and breathable warmth with the added durability of nylon. Engineered stretch provides unrestricted movement whether you're riding, hiking, traveling, or tackling everyday tasks. The lightweight 145 GSM construction makes it ideal as a base layer during winter or a standalone shirt during cool weather, while offset shoulder and side seams reduce bulk and improve comfort under jackets and packs. Whether you're logging miles on the trail, setting up camp, or spending a long day outdoors, the Mesa Falls delivers dependable comfort without overheating. It is the kind of layer you forget you're wearing until you realize everyone else is complaining about the temperature.
