A hood that envelopes a hardhat and an air conduit assembly. The hood has a viewing window and defines a breathable air zone for a user. An aperture in the back of the hood allows a coupling port, which is part of the air conduit assembly, to extend out of the hood and couple to a source of filtered supplied air.

A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin, an intake aperture formed in the frame, and an intake air filter covering the intake aperture. The device includes an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device and an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet. The device also includes an exhaust aperture formed in the frame and an exhaust air filter covering the exhaust aperture. The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component comprising a first portion that is air permeable configured to cover the frame and filters and a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

Various hard hat fan systems are provided. In a certain embodiment, fan system includes an impact absorbing layer with a channel that defines a recessed surface which extends into the impact absorbing layer away from an inner surface of a shell of a hard hat. Together, the inner surface of the shell and the recessed surface define a duct configured to provide fluid communication between an inlet of the channel and an air vent positioned along the channel. In another embodiment, fan system includes a mounting bracket with first and second cam levers which may be actuated into a locked position, and first and second channels. When in the locked position, the first and second cam levers bias the edges of a mounting ridge of the shell against the first and second channels of the mounting bracket such that the mounting bracket is retained on the shell.

The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component, at least a portion of which is air impermeable and extends from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

The full-face helmet system comprises a full-facemask that combines the strength of a facemask frame and a reinforcement layer to allow for improved visibility, safety and impact performance, while reducing weight. The full-facemask comprises a reinforcement layer and a facemask frame, the reinforcement layer may be coupled to the external surface or internal surface of a facemask frame. The reinforcement layer may match or substantially match one or more contours of the facemask frame.

Baseball caps to be worn on a person's head are provided. According to one embodiment, a baseball cap includes a strap assembly configured to adjust a tightness of the dome on the wearer's head, the strap assembly including an outer strap attached to a first edge portion of the dome and an inner strap attached to a second edge portion of the dome. The inner strap is configured to be movable within the outer strap, and the first cable is configured to draw the inner strap closer to the first edge portion of the dome and the second cable is configured to draw the outer strap closer to the second edge portion of the dome.

A hardhat having an outer major surface, and an air conduit coupled to the outer major surface. The outer major surface of the hardhat and the air conduit form an air channel for a source of supplied air.
