Color: ILLINOIS BROWN Sizing: There should be enough sizing in each hat to remain throughout the life of the hat. Hat sizes are to be determined by sweatband size. The hat itself shall be one size larger than the sweatband to make it easier to properly fit the trooper. In the event that our normal stock sizes, which include the regular long oval, extra-long oval and wide oval styles, do not fit a trooper’s head properly, it will be the vendor’s responsibility to make whatever necessary measurements that are needed and manufacture those hats to conform perfectly to the trooper’s head. Hat size will be marked in the back under the sweatband as well as another marking outside of the sweatband. Each size marker must indicate the size and if the oval is regular, long oval, extra-long oval or wide oval.
