Dyed/Distressed/Mesh Trucker Hats are made of 100% Cotton material. Some styles also include a 100% nylon mesh back panel. Patches are made of polyester material. Choose from a Variety of styles and colors. (Some are even two-toned). Hats are one size fits most. Hand washing is recommended. Artwork is handmade, and some styles are distressed, therefore your hat may contain small blemishes that do not take away from the hat but add uniqueness to it.
