Keep your core warm and allow your arms to swing freely with the McAlister Down Waterfowl Shooting Vest.. Outdoor adventurers have known for years that the key to staying warm is keeping your core warm. We at McAlister have taken it one step further. We made a personal furnace to keep your body warm. 6.5 ounce wax canvas combined with grey goose down, taffeta lining, two large bellows pockets, large fleece lined handwarmer pockets and fleece lining around the collar. We looked Ol' Man Winter in the eye and said, "Bring it on".
