Sitka’s Ambient Jacket is an excellent addition to any cold weather hunting setup. It comes equipped with 150 grams of PrimiaLoft insulation, a material that provides Active Insulation. This allows the Ambient Jacket to adapt to your needs by trapping heat while you’re sitting and breaths while you’re on the move help keep perspiration manageable. The Active Insulation also helps keep the bulk of your outfit to a minimum by serving as a mid or outer layer depending on your needs. The exterior of the Ambient Jacket is composed of 20D ripstop nylon fabric for durability against brush and briers, and a water repellent finish easily sheds moisture and light precipitation. Other features of the Ambient Jacket include a mechanical stretch to promote a full range of unrestricted movement, and zippered hand and chest pockets for storing your essentials.
