Bump cap is designed as a safeguard against accidental bumping or scraping of the head. Has protective HDPE liner that is removable so the outer cap is fully washable with a plastic brim. Unique size adjuster slides on an elastic strip to give a quick, secure fit. Angled downward to fit under nape of neck. Reflective piping adds extra visibility and therefore safety in all working environments. Holes in the liner match up with two mesh panels on the cap to provide added ventilation for coolness and comfort.
