This is the latest update from the beanie and I am very impressed on how well it stretches. From top to bottom measures 7 inches. The measurement around the hat is 18 inches but stretches to 22 inches and slightly above but has a nice snuggly fit. I love the way it fits like a glove. It has a coarse texture but I love the way it feels on my head I couldn’t have had it any other way.
