Earmuffs are clothing accessories or PPE designed to cover a person's ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears.


Thermal Earmuffs were invented by Chester Greenwood of Farmington, Maine in 1873, at the age of 15.He reportedly came up with the idea while ice skating and he asked his grandmother to sew tufts of fur between loops of wire.His patent was for improved ear protectors. He manufactured these ear protectors, providing jobs for people in the Farmington area for nearly 60 years.

Types of Thermal Earmuffs

There are two main types of thermal earmuffs. One type has a structure similar to large headphones, with a band going over the top of the head. Another type has two round earpieces connected to a thick headband going behind the back of the head. Some headbands are thick and wide enough to warm the ears, and are referred to "earmuffs" when worn and used this way.
