Abstract: A cap strap cover device covers a sizing strap on a cap. The cap has a covering portion with a hemispheric opening adjacent the sizing strap. The cover device includes a padded structure having first and second portions formed by a hinge allowing the first and second portions to fold relative to one another. The first and second portions fold into a folded position around the cap sizing strap. The padded structure includes a perimeter and a display surface having indicia displayed thereon. The display surface is located on the padded structure so that the indicia is visible when the padded structure is in the folded position. A fastener is provided for holding the first and second portions of the padded structure in the folded position around the cap sizing strap. An appendage is coupled to the padded structure and extends beyond the perimeter of the padded structure.

Abstract: A fabric-covered foam rubber pad that is in a semicircular shape with a small slot gap in the center of the foam rubber pad that provides a hinge to allow it to easily fold in half and provide room for the sizing strap of a baseball-style cap. Hooh-and-loop fasteners are attached to one side of the structure so that when placed up, under, and over a baseball-style cap's sizing strap it can be folded in half and secured in place.
