Abstract: A disposable liner is fitted against the inside surface of a sweatband of a cap or hat. The liner functions to absorb moisture and oils, and to eliminate odor. The liner wicks moisture away from a user and may hold moisture away from the hat. The liner may wick moisture to an evaporation region to be evaporated. The evaporation region may be separated from the hat by a cover layer to prevent wicking into the crown of the hat. The liner may be configured to adjust the size, and thus the fit of the hat on the head of the user. To secure a hat on the head of a user, the liner may include a compressible, foamed, polymeric core. The core may be treated with an antibacterial agent and a deodorizing agent for eliminating odors. To one side of the core is attached an adhesive layer for securing the to the sweatband of the hat. The adhesive is selected for firmness yet easy removal and disposal of the liner. The adhesive may be heat-sensitive.

Abstract: A bicycle helmet with an improved retention system uses an adjustable headband and straps to secure the helmet to the user's head.

Abstract: An adjustable protective helmet having a substantially rigid outer bowl-shaped shell sized larger that the user's head, and having inner padding inside of the shell sized to fit on the user's head but with a looser fit than desired. The adjustment structure includes a flexible strap extended through circumferentially spaced slots in the shell to extend both inside of and outside of the shell, to its ends outside of the shell sized to overlap one another. A rivet secures the underlying strap end to the shell. The padding between the shell slots is free from connection with the shell, and the strap in this region overlies the padding between the padding and shell and is secured to the padding. Quick release fastening pads on the overlapping strap ends allow them to be releasibly secured together. The strap can thus be tightened via the overlying strap end from outside of the shell and connected to the underlying strap end to establish the helmet fit desired.
