Honeywell Super Leight USA Single-Use Foam Earplugs offer optimal hearing protection by featuring a Noise Reduction Rating (NRR) of 33. The pre-shaped contoured foam is designed to fit almost any ear canal for comfortable all-day wear. A closed-cell outer layer prevents dirt from building up while the bell shape will ensure maximum noise reduction and slip resistance. The Honeywell Super Leight USA Single-Use Foam Earplugs are available in a patented red white and blue color design that pays tribute to the USA Shooting Team. This selection of earplugs includes 100 pairs.
