Pyramex HP500 Baseball Bump Cap — Two-in-One Bump and Baseball Cap
The Pyramex HP500 bump cap (HP50011/HP50031/HP50041) combines a baseball cap exterior with a removable polyethylene vented shell insert — providing low-impact bump protection in environments where a full hard hat is impractical but bare-head operation is not appropriate. Meter readers, food and beverage processing workers, warehouse and distribution staff, and automotive technicians commonly use bump caps in areas with overhead obstructions that pose laceration and contusion risks without the trajectory force hazards that require ANSI Z89.1 hard hats.
Important: Bump caps are NOT rated under ANSI Z89.1 and do NOT replace hard hats for overhead falling object hazards. Use where OSHA 29 CFR 1910.135 / 1926.100 hard hat requirements do not apply. Always conduct a job hazard analysis to confirm bump cap suitability for your specific environment.

When to Use a Bump Cap vs. a Hard Hat
The critical distinction: a bump cap protects against accidental contact with stationary overhead surfaces (pipes, doorframes, shelving) — it cannot protect against falling or projectile objects. Hard hats rated to ANSI Z89.1 are designed for impact from above and are required by OSHA wherever overhead falling object hazards exist. Bump caps are appropriate in environments like food processing where:
- Overhead hazards are low-height, fixed obstructions — not falling objects
- Full hard hats would be impractical due to low clearances or hygiene requirements
- The facility's risk assessment confirms no ANSI Z89.1 requirement applies
For environments where ANSI Z89.1 protection is required, see the Pyramex Ridgeline Cap Style hard hat, the Pyramex SL Series hard hat, or the Pyramex Ridgeline XR7.
Key Features
Removable Polyethylene Shell: The vented polyethylene insert separates from the baseball cap fabric, allowing the outer cap to be machine washed without damage to the protective insert. This is essential for food processing and healthcare environments where hygiene and laundry programs are mandatory. The shell can be inspected for damage independently of the cap.
Hook and Loop Adjustment: Unlike ratchet hard hats, the HP500 adjusts via a hook-and-loop strap in the back of the cap — continuous adjustment rather than discrete click positions, achieving a closer fit for workers at non-standard head sizes. No tools required; adjustment takes seconds.
Reflective Piping: Hi-vis reflective tape stitched along the cap seams improves visibility in low-light warehouse, distribution, and utility environments. Particularly relevant for the Lime (HP50031) and Hi-Vis Orange (HP50041) colors, which combine high-visibility fabric with reflective trim.
Soft Foam Interior: A foam comfort liner between the head and the polyethylene shell reduces the pressure of accidental contact, functioning as both a comfort pad and a secondary cushion during impacts.
Frequently Asked Questions
The HP500 is a bump cap, not a hard hat. It does not meet ANSI/ISEA Z89.1. Bump caps in the U.S. do not have a standardized rating system — they are typically designed to EN 812 (European bump cap standard) or similar internal performance criteria. The HP500 is not suitable for any application where OSHA 1910.135 or 1926.100 requires ANSI Z89.1 head protection. Confirm your application's regulatory requirements before selecting a bump cap.
Yes. Remove the polyethylene shell insert first, then machine or hand wash the outer fabric cap. Do not wash the polyethylene shell — wipe it with a damp cloth or mild soap solution. Avoid bleach on the fabric cap, which can degrade hi-vis dye. Allow both components to dry completely before reassembling. Most food processing bump cap programs require a documented cleaning interval — the HP500's design supports that workflow.
Common bump cap industries include: food and beverage processing (overhead equipment, low ceilings), meter reading and utility inspection (crawl spaces, confined entries), automotive service (working under vehicles on lifts), warehouse/distribution (shelving edges, conveyor infrastructure), and data center maintenance (cable trays, rack tops). Always verify with your facility's EHS/safety program that a bump cap is appropriate for your specific task.
A hook-and-loop (Velcro-style) strap runs across the back interior of the cap. Pull the strap to tighten, or release to loosen. The adjustment is stepless — any circumference within the range can be set rather than discrete ratchet click positions. This works well for wearing over hair nets, which are common in food processing environments where bump caps are used.
The HP500 is designed specifically for food processing applications. The removable, washable shell and machine-washable fabric cap support facility hygiene programs. Confirm with your food safety coordinator that the specific color and reflective elements comply with your facility's foreign material control (FMC) program — some programs have restrictions on loose reflective tape or specific cap colors for contamination detection purposes.
Black (HP50011) is the standard option for general warehouse and automotive applications. Lime (HP50031) and Hi-Vis Orange (HP50041) add high-visibility fabric for environments with vehicle movement, low-light conditions, or traffic exposure. The reflective piping on all three colors provides additional nighttime conspicuity regardless of base color selection.
Contact Pyramex directly to confirm shell replacement availability for the HP500 platform. Because the shell is a separate removable component, it may be available as a spare — allowing the outer cap fabric to be replaced when worn while retaining a serviceable shell, or vice versa. Check the Pyramex catalog for current replacement part availability.
Replace the polyethylene shell after any impact, if cracked, or if it shows visible deformation. Replace the outer cap when the fabric is worn, the reflective piping loses reflectivity, or the hook-and-loop strap no longer holds adjustment. There is no standard service life for bump caps equivalent to ANSI Z89.1's 2–5 year shell recommendation — follow your employer's inspection and replacement program and Pyramex's guidance.
