Moldex Camo plugs have camouflage color for serious protection. Made of extra-soft, extra-light foam, their tapered shape fits easily into the ear canal. Camo plugs seal gently and snugly without pressure. Their outer surface is smooth, so it doesn't irritate the ear canal. Camo plugs offer the highest independently tested NRR 33Db rating available, making them suitable for most noisy environments. They are independently tested to ANSI S3.19-1974 standards. 100 pairs per dispenser.
