Our warmest jacket yet! We start with premium RDS sourced, natural duck down and add a high capacity 7.4 volt Powersheer XL(R) micro heating system to produce a jacket with superior warmth and comfort. This jacket is stylish enough to wear every day, with the bonus of performance heat when needed during the most extreme winter conditions. The five heat zones deliver hours of warmth and are easily adjusted between four temperature settings, using the integrated touch control button or from a cell phone using our innovative Bluetooth technology and the MW Connect app. It features a water resistant outer shell and a built-in flashlight with cell phone charging powered by our Powersheer XL battery. The Crest Jacket is suitable for both casual day trips, or longer excursions in the great outdoors. | Mobile Warming Crest Down Heated Jacket in Black | Size Small
