Chain Shirt {50gp}{20lbs}

This armor is leather armor with heavy rings
sewn into it. The rings help reinforce the armor
against blows from swords and axes. Ring mail
is inferior to chain mail, and it's usually worn
only by those who can't afford better armor.
The wearer has disadvantage on Dexterity
(Stealth) checks.
