Linen was the most common material for aketons, gambesons, and arming clothes.
Silk was also used, and there is a tale that says that this is because silk against the skin has a tendency to restrict the damage of a wound. Wool also appears to have been common for
cotes and overclothes, though few examples of arming clothes remain save for the cote of the Black Prince, in Canterbury Cathedral; the jupon of Charles the Bold; and a
pourpoint from the 15th century held in the Kienbusch collection, Philadelphia.
