The Mobile Warming Bluetooth enabled 7.4volt Company Heated Jacket is designed for everyday use or high-energy activity in cold, windy conditions. The Company Heated Jacket is made from a lightweight nylon fabric that keeps you warm while blocking wind, light, rain, or snow. It has stylish looks for around town or up in the mountains. The Company is made with a light-weight 5oz 100% nylon outer shell with a quilted 2oz synthetic down core. When it comes to battling winter conditions, the Company uses our exclusive Wind-Shark Protection. Wind-Shark is a complete wind protection technology made of a combination of a breathable, windproof membrane and a water-repellent coating engineered to keep wind, rain, & water away from your body. The Company has a comfortable rib-knit collar and wrist cuffs that keep wind from penetrating the jacket. The Company includes zippered hand-warmer pockets with plenty of room for your phone or other items. The Company Heated Jacket uses our powerful yet light-weight 7.4volt Far-Infrared Heating System. The 7.4volt system has three heating elements, one on the back and two on the chest, that add heat to critical areas that keep your core warm. The Company's 7.4volt heating system can provide temperatures ranging from 135°F on high to 90°F on low. On high, expect up to four hours of heat. On low, the Company Jacket can provide heat for up to 11 hours! The Company has two ways to adjust the temperature. First, the built-in touch control button. With a simple button push, allows you to choose from four heat settings. Second, we've incorporated Bluetooth control with our MW Connect™ app. Through the MW Connect™ app, you can quickly toggle through all connected Mobile Warming devices and adjust individual heat levels to your liking. MW Connect™ allows you to get real-time updates on battery levels.
