The Patagonia Down Sweater Hooded Jacket adds a single-pull adjustable hood to the Down Sweater story, which makes it the version worth reaching for when the route gets more exposed or the forecast turns colder than expected. The hood and PFAS-free DWR shell work together to cover the gaps a collar leaves open, so a single packable layer handles conditions that would otherwise require two. What Our Gearhead(R) Experts Are Saying:"I pack this into its own chest pocket and clip it to my harness loop when the summit push starts. It's light enough that I forget it's there until the wind picks up."
