This men's insulator jacket has become a Patagonia staple for all the right reasons. It's light, compressible, and highly versatile, designed to deliver an unmatched warmth-to-weight ratio and classic style at home any place its cold. It’s padded with third-party traceable 800 fill power European Goose down in a quilted design for maximum thermal retention. It’s then wrapped in a recycled polyester ripstop shell that’s treated with a water-repellent finish to shed light precipitation. The inner lining is also recycled ripstop fabric and is coated with a DWR finish. It features two Vislon zippered hand pockets and an interior chest pocket that has a carabiner loop and doubles as stuff-sack. Nylon-bound elastic sleeve cuffs and a lower hem that tightens with a drawcord via the hand pockets, help this insulator seal in the heat.
