- OPTIMAL COMFORT: Advanced four-flange design creates air pockets that reduce the pressure in the ear canal to eliminate "plugged up" feeling common to other earplugs; flanges are soft for more comfort
- NRR 27 FOR UNPARALLELED PROTECTION: Four internal noise-blocking fins create an interlocking, noise-blocking barrier for a 27 Noise Reduction Rating (NRR), the highest attenuation in multiple-use earplugs
- SUPERIOR FIT: Flanges are rounded to conform to the shape of the ear canal; earplug shape is tapered and elongated to mirror the shape of the ear canal as it narrows internally
- EASY CARRY & INSERTION: Firm, integrated stem allows for easy insertion & removal; red polycord drapes around neck for easy carriage; reusable carry case helps prevent loss and promotes hygiene
- RECOMMENDED INDUSTRIES: farming, chemical, construction, law enforcement, manufacturing, military, mining, municipal, oil & gas, pharmaceutical, steel, transportation; 50 pairs per box
