Hot Bags Care & Usage Instructions. The large size HOTBAG, HB-2, holds up to six 16" pizzas and has all the features of the standard size bag. Both 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 sold separately. For 6 or more bags, it is more economical to purchase a Six position Power Distribution Unit.
