MATERIAL: 100% polyester. Hand wash cold. ✔️GREAT LOOK: This bucket has two unique looks; in the daylight, the hat appears as a solid color; at night, when headlights are flashing or a when using camera flash, the hat turns into a metallic, iridescent color due to its reflective nature. NOTE: Our marble style hat is only partially reflective. The primary color of these hats will not change with flash, but the areas that appear as black will. See second picture. ✔️GREAT QUALITY: This sturdy cap is both adjustable and bendable. The brim contains a bendable wire allowing for you to shape the hat to your liking. Inside the hat there is a sweatband and a detachable chin strap. ✔️GREAT FIT: One size fits most. There is an adjustable toggle in the back of hat to make the hat tighter (SOLID HATS ONLY). Brim length is approximately 2.5”. Height from top of brim up is approximately 3.5”. Inner circumference is approximately 25”. Has a snug, yet comfortable fit.
