A jack of plate is a type of armour made up of small iron plates sewn between layers of felt and canvas. They were commonly referred to simply as a "jack" (although this could also refer to any outer garment). This type of armour was used by common Medieval European soldiers as well as by the rebel peasants known as
Jacquerie.
The present day equivalent is perhaps a
bullet-proof vest
A bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from firearm-fired projectiles and fragmentation from explosions. ...
.
The jack is similar to the
brigandine. The main difference is in the method of construction: a brigandine is
riveted whereas a jack is sewn. Jacks of plate were created by stitching as many as 1000 small overlapping squares of iron between two canvases.
The garments weighed about , which made them much more acceptable to the wearer than solid breastplates. They also offered a tactical advantage: they allowed soldiers to rest the butts of weapons firmly against their shoulders, which wasn't feasible with smooth-surfaced plate armours. Unlike plate they made no attempt to be bulletproof.
Jacks were often made from recycled pieces of older
plate armor, including damaged brigandines and
cuirasses cut into small squares.
The jack was particularly favoured in Scotland. After the death of
James V of Scotland in December 1542,
Cardinal Beaton ordered the keeper of the royal wardrobe
John Tennent to give the king's jack of plate to his lawyer
Adam Otterburn. In July 1547,
Regent Arran had a new jack covered with purple taffeta, then changed his mind, choosing purple velvet. During the rebellion against
Mary, Queen of Scots known as the
Chaseabout Raid it was said in September 1565 that while her husband
Lord Darnley wore a gilt
corslet or breastplate, the rest of the lords "after their country fashion" wore jacks.
