Loaded with PrimaLoft Black insulation through the body 80 gram and sleeves 60 gram, the Under Armour Boys' Coldgear Infrared Micro Insulated Jacket is a versatile 3 season jacket for cool to freezing weather. Its tough nylon exterior features a water repelling DWR treatment, which sheds passing showers from soaking through. Add in a MagZip closure that clicks and holds in place for an incredibly easy wearing jacket. Setting this puffy apart from the rest, Under Armour uses its Coldgear Infrared Coating to retain fiery body heat within the jacket. Used in conjunction with the jacket's low bulk synthetic insulation, you'll find that Infrared Coating heats him up faster and retains warmth for significantly longer than traditional jackets. Additionally, the zippered hand pockets contain a media port within the left pocket for seamless audio integration.
