Uncorded earplugs are made of nonflammable, dermatologically safe foam. PVC foam is nonirritating. Slow-recovery, low-pressure foam conforms to the shape of the ear canal for enhanced comfort and wearability. Moisture-resistance helps maintain a consistent expansion time, even in humid environments. Reusable Pillow Pack helps keep earplugs clean when they are not being worn. NRR 29-decibel earplugs fit a wide range of ear canals and are tested to ANSI S3.19-1974.
