3M™ PELTOR™ Optime™ 105 Earmuffs Over-the-Head, Hard Hat Attached, Behind-the-Head
Earmuffs are a type of personal protective equipment (PPE) that is used to protect the wearer’s ears from excessive noise pollution, dust or temperature variations, especially cold. They are made of thermoplastics and sponge and are shaped like a pair of cups. These cups are usually attached on the outer-ends of a steel or plastic headband to fit over top of the ears and cover them tightly.
