A modern hauberk made from 1.5 mm diameter wire with 10 mm inner diameter rings weighs roughly 10 kg (22 lb) and contains 15,000–45,000 rings.

However, modern chainmail is generally made from lighter metals such as aluminum or titanium.. This is opposed to the iron or simple alloys of the medieval period.
