ulster
A long, loose overcoat made of wool or other rough material, often called a greatcoat, which sometimes features an attached shoulder cape covering the back and sleeves, and which can sometimes be buttoned in front.
ulster: the worksite overcoat that won't quit
An ulster is a heavy wool overcoat designed for durability and warmth in industrial and outdoor work environments. Unlike tailored dress coats, it is cut generously to fit over layers of work clothing and to allow free movement of the arms and shoulders. The fabric is typically a rough, twilled wool weave, often in neutral colors like gray, brown, or navy, chosen for resistance to snagging and easy cleaning. The coat reaches at least to the knees and sometimes to mid-calf, providing leg protection from wind, rain, and minor splashes of industrial materials.
The defining feature of many ulsters is the shoulder cape, a separate piece of fabric that drapes across the back and extends partway down the sleeves. This cape serves a practical function: it sheds water more effectively than a standard shoulder seam and protects the back and upper arms from overhead moisture or light rain without restricting arm movement. Some ulsters feature this cape; others omit it entirely. The front closure is typically large buttons or toggles, spaced wide apart for easy fastening and unfastening while wearing gloves or when hands are cold.
Ulsters were widely worn throughout the 20th century in factories, shipyards, mines, and construction sites where workers needed durable outer layers that could take punishment and still function. The coat is heavy enough to provide genuine insulation but loose enough that it does not bind when the wearer bends, climbs, or reaches. Wool, being hygroscopic, actually provides some warmth even when damp, making it superior to cotton for wet industrial work. The rough weave also resists snagging on machinery edges and does not pill easily.
Where the name comes from
The term ulster derives from Ulster, a region in Ireland historically known for wool production and the manufacture of heavy overcoats. The style became associated with this region's textile output and was exported widely during the 19th and early 20th centuries. The name stuck even when ulsters were manufactured elsewhere, much as "denim" refers to a weight and weave rather than origin.
Today, the ulster is largely displaced in industrial settings by modern synthetic jackets and Gore-Tex rain gear that are lighter and easier to care for. However, the ulster remains in use in certain cold-weather trades and in heritage or traditional manufacturing contexts where its proven durability and low cost justify the weight and care required. Vintage ulsters are also sought by outdoor enthusiasts and military reenactors for the same reasons workers chose them a century ago: reliability and honest construction.
