Dominic Mancini wrote this about the archers in Richard III army in 1483 as they arrived at London:
"There are hardly any without a helmet, and none without bow and arrows; their bows and arrows are thicker and longer than those used by other nations, just as their bodies are stronger than other peoples’, for they seem to have hands and arms of iron. The range of their bows is no less than that of out arbalests (crossbows); there hangs by the side of each a sword no less long than ours, but heavy and thick as well. The sword is always accompanied by an iron shield… They do not wear any metal armour on their breast nor any other part of their body, except for the better sort who have breastplates and suits of armor. Indeed, the common soldiery have more comfortable tunics that reach down below the loins and are stuffed with tow or some other material. They say that the softer the tunic the better do they withstand the blows of arrows and swords, and besides that in summer they are lighter and in the winter they are more serviceable than iron."
Richard's archers wore stuffed jacks, most had helmets, and all had a sword and buckler. Based on that Lord Grey's Retinue archers should have
the following:
Clothing:
Shirt and Braies (A set for each day of an event is recommended)
Doublet (A summer and a winter weight wool doublet is recommended)
Hosen
Points
Acorn hat
Gown - For civilian wear (A summer and a winter weight gown doublet is recommended)
