Perfect for reenactors or stage performers who need authentic looks, but don't need authentic weight. This extremely light weight chainmail utilizes aluminum rings, riveted for durability and only weighs about 2 lbs! Even if you wear it all day long you'll hardly notice the weight. The outer diameter of the rings are about 1/2". It can be worn with or without a helmet. We recommend keeping this mail oiled at all times. While riveted chainmail and aluminum chainmail generally cost more than regular steel chainmail due to materials and intensive labor, when the two are combined, the quality and convenience make it all worth every penny.
