JSP Bump Caps are a novel, lighter-weight alternative to true hard hats. They help to offer extra protection against incidental bumping or abrasions. You gain protection, but with the amazing comfort of a baseball cap. Used extensively in assembly operations and many other applications, JSP's bump caps are available in three bill lengths - Standard, Short, and Micro - and in multiple cover colors. All JSP bump caps include the same hard shell; only the brim and color choices will vary. All include an adjustable elastic strap for a custom fit.
