This thermal blanket will pay for itself in wood pellets saved when grilling in cold temperatures. Fits the Jim Bowie grill by removing the handle, placing the blanket over the grill, reattaching the handle thru the grommets. Magnets hold the rest of the blanket over the dome. Leave on all Winter and remove when the weather warms up. This is a customer favorite !! Check out www.greenmountain.com for more information. Also available for Daniel Boone and Davey Crockett grills.
