The Mr. Heater® 18B Big Buddy Carry Bag is the best and easiest way to transport your 18B heater and accessories to the job site, fishing shack or wherever else you need to bring the heat. Great for storage, too. The Bag itself is made from 600-denier polyester, and 18B heater easily fits inside, thanks to the oversized openings. Two side pockets each allow for 1-lb. tank storage, and the rear pocket works great for storing hoses and other accessories. It's a must-have Bag to go along with your 18B.
