Expanding on the heating tech Ralph Lauren debuted for Team USA at the 2018 Winter Olympics, the Polo Glacier Heated Jacket uses multiple techniques to keep you warm. Powered by a Polo-branded Mophie battery, its featherweight heating system uses heat-conductive carbon and silver ink to provide up to 11 hours of warmth, with the option to adjust things via the RL Heat app. It's insulated with ethically-sourced, 750-fill-power white duck down, so it's effective at holding in heat even when the active system isn't running, and the water-repellent ripstop shell keeps the weather at bay. While the Glacier comes in metallic silver or matte navy, the heating technology is also available in the NASA-inspired Polo 11 jacket.
