A jerkin is a man's short close-fitting jacket, made usually of light-coloured leather, and often without sleeves, worn over the doublet in the sixteenth and seventeenth centuries. The term is also applied to a similar sleeveless garment worn by the British Army in the 20th century.
The buff jerkin refers to an oiled oxhide jerkin, as worn by soldiers.
The origin of the word is unknown. The Dutch word jurk, a child's frock, often taken as the source, is modern, and represents neither the sound nor the sense of the English word.
Leather jerkins of the 16th century were often slashed and punched, both for decoration and to improve the fit.
Jerkins were worn closed at the neck and hanging open over the peascod-bellied fashion of doublet. At the turn of the 17th century, the fashion was to wear the jerkin buttoned at the waist and open above to reflect the fashionable narrow-waisted silhouette.
By the mid-17th century, jerkins were high-waisted and long-skirted like doublets of the period.

During the First World War, the British army issued brown leather jerkins to the troops as a measure to protect against the cold but to allow freedom of movement. These garments generally had four buttons and were lined with khaki wool. They were practical, hardwearing and extremely appreciated by officers and other ranks alike. By the time of the Second World War, the leather jerkins were still on issue to all the Commonwealth forces and were universally popular. Jerkins made in Canada were dark brown with black wool linings and differed in general appearance from the British jerkins.
