Patagonia designed the Nano-Air Ultralight Full Zip Hoodie as a versatile insulator for active alpine pursuits. The shell and lining comprise recycled ripstop polyester fabric, which is lightweight, abrasion resistant, and has mechanical stretch to enhance mobility. Filled with FullRange™ synthetic insulation, the warm yet highly breathable fibres aid temperature regulation. It will keep you comfortable whether you're moving or resting, making it an excellent choice for stop-start activities like climbing and scrambling. Features include an insulated low-profile hood, a zipped chest pocket that doubles as the style's stuff sack, and low-bulk cuffs. Articulated patterning and a regular fit make it easy to wear with other layers.
