Very nice, well made fiberglass blanket. Very soft and comfortable to wear. The delivery was very fast, 2 days, thank you very much! with difficulty reaching a high temperature in the cold. This blanket has solved this problem and also keeps the temperature stable. I fold it a few times to fit the width of the grill lid and it's very effective for insulation. and back to balance it from slipping. but it's easy to do. although you may need to consider how to keep the vents clean. I have a Traeger wood pellet grill, so I fold the comforter tightly on top so it doesn't fall down my back and cover the vents on my back. The ceiling is darkened by the smoke, but it's harmless.
