Hot Bags Care & Usage Instructions. The HB-XW Extra Wide HOT BAG holds up to three 18" or four 16" pizzas. It has all the features found in the HB-1 and the HB-2 HOTBAGS. All HOTBAGS feature a clear plastic pocket for receipt slips, Velcro fasteners and a convenient strap handle on the bottom. Bags have two thermostat controlled heating elements that are built into the top and bottom of the bag for constant even heat. It is made of 400 Denier nylon for durability and Dupont's Thermoloft insulation for maximum heat retention. The HOTBAG is extra strong, light weight and it's easy to clean and handle. The heating elements do not interfere with the use or cleaning of the HOTBAG. The 6' power cord which plugs into the cigarette lighter and has a quick release connector at the bag, is sold separately. Power Distribution units with the appropriate PDU Input Power Cords are also sold separately. For 6 or more bags, it is more economical to purchase a Six position Power Distribution Unit.
