The R1 Air Zip Neck by Patagonia is a lightweight, breathable baselayer designed for cold-weather high-output activities. It features 100% recycled polyester jacquard fleece with super soft hollow-core yarns and a zigzag texture. The fabric wicks moisture, dries quickly, and includes durable odor control. A half-zip allows temperature regulation, and an external zippered chest pocket adds convenience. Offset shoulder seams enhance comfort, while stretchy bindings at the hem and cuffs improve fit. Fair Trade Certified™ sewn.
