Chinstrap beard

Henry David Thoreau sporting the chinstrap beard.

The chinstrap beard or "neckbeard" is a type of facial hair that extends from the hair line of one side of the face to the other, following the jawline, much like the chin curtain. Unlike the chin curtain though, it does not cover the entire chin. It was fashionable from the late-18th century through the mid-19th century in Europe, and later in Russia and Japan. It is also worn today, but in an alternative version by athletes such as Dwyane Wade, Elvis Andrus, Raymond Felton, and David Ortiz among others. This beard is also known as the fat-man's beard because it can cover up fat rolls under the chin. The chinstrap is also one of the easiest beards to grow because certain individuals can't grow a full beard on the face, but most men can grow on the neck and sides of the face.
