The Skullerz 8946 Standard Baseball Cap is a customizable baseball cap designed to integrate with the best-selling Skullerz 8945 Universal Bump Cap Insert (included) for use on worksites where hard hats arent required, but added head impact protection is still needed to shield against bumps, scrapes, bruises and other minor head injuries. Designed with logo customization in mind, this baseball cap provides a never-before-seen combination of form and function. In addition to the bump cap-compatibility, the hat features reflective brim piping for added visibility, a one-size-fits-most adjustable hook & loop closure and a mesh back half for breathability. The Skullerz 8945 Universal Bump Cap Insert is a lightweight, impact-resistant shell featuring an interior foam pad for additional impact protection and comfort. Worn alone, this customizable baseball hat is a stylish option for everyday wear.
