The WW1 US AEF Summer Weight Riding Breeches are original military-issue trousers worn by members of the American Expeditionary Forces during the First World War. Designed for mounted troops, these breeches feature a tapered-cut leg and reinforced inner knee panels to provide durability and ease of movement while riding. Constructed from lightweight khaki cotton, they were intended for wear in warmer climates, offering greater comfort compared to heavier wool variants. The breeches include button fly closures, adjustable lacing at the calf, and belt loops or button tabs at the waist depending on the manufacturing period. Commonly used by cavalry, artillery, and some officers, this garment reflects American military uniform standards of the 1917–1918 period. Surviving examples may exhibit manufacturer markings, dates, and service wear consistent with field use. These breeches are representative of typical U.S. Army summer uniform components from the era of the First World War.
