H415 - Disposable Earplugs, Therma-Soft, Corded, 100/box NRR: 30dB

NRR=30dB Tested at an independent NVLAP accredited laboratory. Manufactured from super-soft PVC for its unique performance characteristics. New and improved foam responds to body heat by getting softer with use. The only foam specified by the United States Military. Optimal recovery time allows for deeper insertion, more secure fit and less backing out which is particularly important for those with smaller ear canals. Therma-Soft 30 provides an excellent seal for every user.
