Its eyes are getting heavy, it's starting to feel veeeery sleepy, and if you put the cover on it, it'll fall into a deep sleep. The Big Green Egg has once again done its fragrant best to fill all the hungry stomachs. Of course, you can't leave it out in the cold, so you put its Big Green Egg cover on it. This coat is water resistant, breathable, and protects the green egg from any weather conditions. The cover is made of vinyl, and although a vinyl coat doesn't sound too appealing, the Big Green Egg is happy with it.
