Pictured on right of photo. From Patagonia's website: "Cutting-edge routes require adaptability, which is why our Jacket has become a mountain staple. It can be worn as a stand-alone jacket when you're on the go or an insulating layer when the mercury plummets. The stretchy, variegated-fiber fabric yields superb warmth, breathability and compressibility along with minimal weight. Stretchy fabric under the arms and inside the collar enhances moisture-wicking, and the pliable body fabric affords unrestrained movement. Reverse-coil zippers throughout (welded-in on the chest and hand pockets)."
