The Hat-Trap is designed to protect an officer's campaign hat from crushing, fading and brim warping when the hat is not being worn. The Hat-Trap is made from extremely tough HDPE allowing it to stand up to extreme temperatures, keep dust from damaging the hat and keep the brim pressed. One handed operation allows the user to easily open, retrieve the hat and close. The Hat-Trap features a single latch system, a hat strap tray and a recessed area for hat braids. An integrated carrying handle makes transporting for storage or travel easy. One size fits all.
