The smaller and finer worked the rings are, the more protection offered. We are proud to offer the peak of the armorer’s art and patience as it pertains to mail. The butted, 17 gauge steel rings are only 3/16″ round, providing unsurpassed protection. Incredibly dense, the rings provide the ultimate defense against whatever comes your way. As a result of the number of links needed, this shirt is not lightweight. Length is approximately 31″ with a 55″ chest.
