The Access Down 1.0 jacket provides lightweight down insulation that you can keep on during cold-weather activities and stash in your pack when things heat up. The jacket’s 700-fill goose down keeps you warm while a 20D nylon face fabric that’s finished with a DWR coating provides light weather resistance. Stretch woven fleece side panels add range of motion and packability. Two zip hand pockets, an internal zip pocket, and stretch knit cuffs round out the features of this cold-weather active-insulating layer.
