Arming doublets were worn under plate armor from the 15th century onward. The laces on the doublet allowed armor pieces to be directly attached to it. The arming doublet was a development of the gambeson and the 14th-century pourpoint. The inside of the doublet is padded, protecting the body from blows delivered to the armor. In the late Gothic style (1450–1500), voiders and a chainmail skirt (gousset) were often added to the arming doublet. In late 15th-century Italy, it even became a civilian fashion: men who were not knights wore arming doublets, likely because the garment conveyed status and chivalric association.
This arming doublet is ideal for 15th–16th century reenactment and LARP. It is made of 100% cotton and can also be worn comfortably on warm days. The sleeves are detachable and secured with laces.
