This original WW2 United States medical armband is a wartime reversible example, produced for use by American medical personnel and Red Cross–affiliated staff during the Second World War.

Constructed from plain off-white cotton drill, the armband features a sewn red felt cross on one side and a stitched red outline cross on the reverse, allowing it to be worn either way depending on circumstance or role. This reversible design is characteristic of American wartime manufacture and is far less commonly encountered on British equivalents.

The armband fastens with two original plastic buttons and a series of buttonholes, providing adjustability to fit over uniforms, jackets, or heavier outer garments. When laid flat and undone, the armband measures approximately 16 inches in length, consistent with US wartime patterns designed for universal fit.

Examples of this type were worn by US Army Medical Department personnel, medical orderlies, and Red Cross staff, both in training environments and operational settings. Unmarked examples such as this are typical and should not be seen as unusual.

The armband remains in original, used condition and shows scattered age-related spotting and staining to the cotton fabric on both sides, consistent with wartime use and long-term storage. The felt cross remains securely attached with intact stitching, and the reverse outline cross is clearly visible. All buttonholes are present, and both plastic buttons remain firmly in place. No modern repairs or alterations are evident.
