How many ribs are part of the Brush helmet's trademarked design?

• A. 4 ribs
• B. 5 ribs
• C. 2 ribs
• D. 3 ribs

Answer: (D)

Three raised ribs across the helmet crown make up the Brush helmet’s trademarked design. This specific ridge count creates the distinctive silhouette that identifies the brand and contributes to the shell’s rigidity where it matters most. Because the trademarked look hinges on exactly three ribs, that count is the correct one. Counts like two, four, or five wouldn’t match the recognized design and branding, so they don’t fit the official appearance. Recognizing this feature helps you quickly identify the model in real-world use and drills.
