Black adjustable wide brimmed visor /hat. Can adjust to make it tighter to fit your head. The material feels like satin . Width Measurements in the front is 5.5 inches and tapers and gets smaller towards the back and is 3.5 inches. I think the inside is plastic to give it structure but it’s bendable. I only wore this once at a festival when I left my hat at home. Great for traveling, hiking or gardening!
