Loaded with PrimaLoft Silver Downblend, the Under Armour Girls' ColdGear Infrared Aura Insulated Jacket delivers the best characteristics of down and synthetic insulation. In fact, PrimaLoft Silver Downblend traps fiery body heat with its high loft down clusters while avoiding total heat loss in damp to wet conditions, thanks to its partial synthetic composition. Further aiding the jacket's ability to repel nasty weather and retain heat, its Storm1 water repellent beads off passing showers and snow flurries. Under Armour even threw in its ColdGear Infrared lining that retains body heat with its thermal reflective coating. Ultimately, this technology retains heat much longer than a standard jacket, meaning she'll stay pleasantly warm through winter's worst weather.
