An interesting field test of musketeer armour. Historically, musketeers did not wear armour, because it would have got in the way of the musket butt when aiming. But the officials of Jamestown apparently tried to find a way to modify the existing armour in order to protect their musketeers better. Check out this test run by Jamestown Rediscovery group to find out how it goes.
Very interesting, but it is quite understandable that the musketeers were not equipped with armour more widely. Not only was it expensive, but the musket alone was a heavy piece to carry around and it would have been hot and uncomfortable work while wearing an armour.
