Classic Plus are longer than Classic earplugs to fit deeper into the ear canal and provide a higher level of protection. Slow-recovery foam helps ensure comfort and minimize pressure. Bright yellow color provides a quick visual compliance check. Dermatologically safe foam is non-irritating, nonflammable, and moisture-resistant. Our convenient pillow pak keeps each pair clean and available for re-use. NRR 33dB. ANSI S3.19-1974; CSA Class AL.
