Moldex Softies are made of extra-soft, extra-light foam. Their tapered shape fits easily into the ear canal. Softies seal gently and snugly without pressure. Their outer surface is smooth, so it doesn't irritate the ear canal. These 100% PVC-free earplugs have a bright, radiant orange color, making compliance checks easy. Softies 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.
