An illuminable helmet assembly is disclosed. The helmet assembly may include a helmet body having an outer shell, an energy management layer and a fit system. A light diffuser is coupled to an outer surface of the helmet body, the diffuser having an illumination surface with an outer perimeter and defining a footprint of the illumination surface extending inward from the illumination surface to a center of the helmet body. A light source is positioned adjacent to and in some cases outside of the outer perimeter and the footprint of the illumination surface. The light source is positioned to emit light toward the illumination surface at an acute angle to the illumination surface.

Various embodiments of helmets and methods of their manufacture are disclosed. In some embodiments, the helmet includes a helmet shell having a helmet shell edge and/or a mounting location for mounting an accessory to the helmet shell. A material that is adherent to the helmet shell may be sprayed onto the helmet shell edge of the helmet shell to form a trim. Alternatively, the material may be sprayed onto a portion of the helmet shell associated with either a mounting location for mounting an accessory or a position for a mounted accessory.

Embodiments of fiber surface finish enhanced flocked surface impact force absorbing structure include a plurality of flock fibers disposed on a substrate, a surface coating applied to the plurality of flock fibers, and in another embodiment, a divider fabric bonded to the tops of flock fibers.

A helmet for rotational energy management can include an outer energy management layer comprising an outer surface and an inner surface opposite the outer surface. The inner surface can comprise a first slidable finish comprising a first glaze comprising a thickness less than or equal to 2 millimeters (mm). An inner energy management layer can be disposed within the outer energy management layer and further comprise an outer surface oriented towards the outer energy management layer and an inner surface opposite the outer surface. The outer surface can comprise a second slidable finish that directly contacts the first slidable finish. The second slidable finish can comprise a second glaze comprising a thickness less than or equal to 2 mm. A space between the first slidable finish and the second slidable finish can be devoid of a lubricant and devoid of any interstitial slip layer.

A reconfigurable helmet and exemplary uses thereof are disclosed. The reconfigurable helmet includes a first portion that includes an outer shell and a second portion that includes a liner. The first portion can translate relative to a second portion to expose one or more functional layers for removal or replacement. A user can configure and reconfigure the helmet by adding, removing, or replacing one or more of the functional layers.

A firefighter protective hood that protects the coat/helmet/self-contained breathing apparatus facepiece interface area of a user, and a firefighter protective glove that protects the hand and wrist of the user are provided. The firefighter protective hood and glove respectively include a hood-shaped structure and a glove-shape structure. The hood-shaped structure and the glove-shaped structures each include a body-contacting layer made of a fabric of flame-retardant regenerated cellulose fibers. The structure and composition of the body-contacting layer promote comfort of the user and evaporative cooling. Outer layer(s) extend outwardly over the body-contacting layer and act as thermal and mechanical barriers. The combination of such layers allows maintaining relatively high perspiration transmission and evaporation, and substantially good thermal and mechanical properties.
