Rothco's ball cap style tactical operator hats are made with 100% cotton rip-stop for durability. The operator hat has 4 reinforced air vent holes and color matching hook and loop closure for an adjustable fit. In addition to maintaining the classic style of a baseball cap, Rothco's tactical operator hat features enhanced tactical elements including a 1 1/4" x 1" loop patch on top and a 3 1/2" x 2" loop area on the front of the cap ideal for flag, unit or morale patches (that are sold separately). One size fits most.
