The Deer Mullet Brand Rope Hat! This is a Concho brand Loden (green) colored hat with a gray rope. It has a patch with the Deer Mullet Brand on it. The side has the circle M logo of MKH Hats and Apparel, started by Micah Heinold (whose initials are MKH.)
These hats are snap back so can be adjusted to fit almost any size.
