1st off, i have always wanted to get these types of hats and i have to say; it is well worth it! so the hat is made of pretty good material. i have a rather big head so it seemed a bit small on the top of my head, but nothing that would stop me from wearing it. it only has two buttons for size adjustment so, not much room for play there. i wore it for a few hours and it seemed to fit better. good buy!
