Size is Large to Extra Large. Made from 14 gauge dirty aluminum wire wound into jump rings with a 3/8" interior diameter and linked in a European 4-1 pattern. This hauberk easily weighs 15 pounds. Aluminum does not rust. The finish on the rings may start off a bit shiny but will take on a dull patina over time - giving the item a more authentic look. This hauberk has half-sleeves.
