The Mobile Warming Bluetooth enabled 12volt Foreman Heated Jacket is a real work jacket with classic looks and heavy-duty construction. Designed for a rancher, construction worker, lineman, or anyone who works outside in the cold. The Foreman is constructed of heavy-duty 5 oz 100% Cotton Canvas Outer Shell. Featuring a thermal-lined hood with a drawcord closure to keep the wind out and a quilted polyester full sleeved thermal liner, this jacket is unmatched. The Foreman has heavy-duty zippers and loads of pockets for storage. Powered by a 12 volt Lithium-Ion battery, the Foreman keeps you cozy with our Ultra-lightweight heating system. Featuring a USB port to charge your mobile devices and a powerful built-in LED flashlight, the Foreman has substantial heating elements, two in the chest and two on the back. It can provide heating temperatures ranging from 135°F on high to 90°F on low. On high, expect up to three hours of heat. On low, the Foreman can heat up to 11 hours! The Foreman has two ways to adjust the temperature. First, the built-in touch control button.
