Made from thick, sturdy plastic so it's not flimsy at all. It has elastic on either side that you tie to fit your head, so it has a stretchy, comfortable fit. It fit my 10 yr old son with plenty of room to spare, so would definitely fit an adult head. The gold color is very dull (even a little more dull than what's pictured), so I spray painted it a nice, bright true gold. It was perfect for my son's Zeus costume!
