Patagonia M's R1 Air Jacket is a lightweight, technical fleece jacket designed for activity in cool conditions. The fabric consists of 100% recycled polyester in a jacquard construction with hollow-fibre yarns that efficiently wick moisture, dry quickly and provide excellent breathability as intensity increases.

The distinctive zigzag pattern reduces bulk, improves airflow and makes the jacket easy to compress when packing down. The slim fit and full-length zip allow practical temperature regulation and make the jacket straightforward to put on and take off in changing conditions.

The shoulder seams are repositioned away from the top of the shoulders to sit comfortably under pack straps, reducing friction and increasing durability. The jacket features a zip chest pocket for small essentials, and two front pockets with minimalist zips that keep volume low without compromising function.

The cuffs and hem are finished with quick-drying woven binding that provides a good fit and added durability. The jacket is made in a Fair Trade Certified™ factory and combines warmth, low weight and excellent breathability for mountain tours, trail use or everyday wear.
