With the Chiefs Cutter and Buck Post Alley Vest chilly weather doesn't stand a chance. The channel quilting at the front and back body is filled with low profile 160gm insulation, allowing warmth that doesn't bulk up. The diamond quilting at the back yoke, reflective piping details, and exposed full zip further the feminine fashion. The mock neck, angled shoulder, elastic binding at the armhole, and zippered front pockets ensure it fits like a glove. 100% polyester.
