During the 15th century, plate armor was developing at a quickened rate. In order to attach these plates, a knight needed a doublet that would allow for the versatility of his armor. This doublet is one of the best we have ever offered. Made of 100% black cotton canvas, it is filled with organic cotton felt, which allows body heat to escape better than poly-fill. Multiple eyelets allow the you to move your pieces to the best position possible. Multiple lacings tipped with sew-on aiglets are included. M, L, XL or XXL.
