About Hearing Protection

Earmuffs and earplugs are rated by the Noise Reduction Rating (NRR) guidelines, which are enforced by OSHA.

Earmuffs should be worn with the specified fit to offer proper protection and noise reduction.

You can wear Style C earmuffs over the head, behind the head, and under the chin.

Hard Hats with Face Shield and Earmuffs

Cap Brim with Solid Lens

Brimless with Mesh Lens

These hard hats give all-in-one head, face, and ear protection. You can lift the face shield and earmuffs when not in use. Turn the ratchet in the back to adjust for a secure fit.

Type I, Class E hard hats protect against blows to the top of the head only and are proof-tested at 20,000 volts.

Type II, Class C hard hats protect your head from blows to the top and the sides. A foam shell absorbs impact to reduce force on your neck and head. These hard hats have chin straps, so they stay secure when working sideways, upside down, and in the wind. Designed for forestry, they have a corrosion-resistant steel mesh lens that guards the face while letting a cool wind in. They also have ventilation holes to increase air circulation and maintain a comfortable temperature. Their ratchet knob pivots to fit around ponytails and bandanas. They have not been tested for electrical protection.
