1. A hard hat system comprising:
a hard hat comprising a shell formed from a rigid material, the shell comprising an external surface and an internal surface that defines a cavity configured to receive a head of a wearer;
a brim guard detachably coupled to the hard hat such that a front of the brim guard is positioned at a front of the hard hat, the brim guard comprising a visor that extends radially outward from a center of the hard hat; and
a locking mechanism coupled to the brim guard, the locking mechanism configured to actuate between a locked position and an unlocked position, the locking mechanism preventing the brim guard from sliding vertically with respect to the hard hat when the locking mechanism is in the locked position, the locking mechanism sliding along a horizontal axis when transitioning from the locked position to the unlocked position.
