Designed for athletes who practice their sports on the mountain, the Under Armour Men's Ultraloft Mountain Vest will keep you warm without weighing you down. Made with wind- and water-resistant polyester shell fabric, this insulated vest is stuffed with ArmourLoft Poly Microfill for lightweight warmth. When the temps are cold but you are working hard, ColdGear technology features a double-sided fabric that wicks moisture away from the skin and circulates body heat to keep you dry and warm. The collar stands up for extra neck protection and 2 zippered hand pockets offer a place to stash small essentials. This synthetic vest packs into its own pocket so you can always bring it with you for backup. With a full, loose fit, you'll have a wide range of motion when you're wearing the Under Armour Ultraloft Mountain Vest for men.
