Best Use: All ConditionsWhether it’s over the course of an entire season, or just one day of hunting, the all-new Precision Hunter Vest comfortably scales up or down with your layering system—solving the problems of typical one-size-fits-all hunter orange vests. While layered up in the cold early morning, use the extended strap with magnetic buckle to fit over insulated outer layers. As the day warms up and layers come off, wear it zipped up and streamlined to comfortably fit over a single base layer, without excess bulk. Features include high-stretch mesh side panels for added versatility and comfort, and zippered hand pockets for secure and convenient storage. In addition, the vest may be worn under or over a bino harness using the extended strap. Its Blaze Orange color and total square inches satisfies the legal requirements in most states.
