Maille, or mail, or "chain mail" (as popular culture and web search engines call it) was the #1 armor from Roman times up through the 14th century, and was still used on the battlefields of eastern Europe and central Asia well into the 20th century.
This knee length full-sleeve hauberk is crafted of alternating rows of 9mm dome-riveted flat rings and punched solid rings. The alternating rings makes this a very strong, combat-worthy maille.
Available in sizes 48" and 60". These sizes relate to the actual circumference of the mail garment rather than to chest size. The 48" is about 39" from shoulder to hem and will fit up to about a 44" chest dimension measured over a gambeson an/or arming clothes, and the 60" size is about 42" from shoulder to hem and will fit up to a 54" chest dimension, again measured over the gambeson and/arming clothes.
