Chain armour

Mail or 'chainmail is armour which had been crafted out of a series of interlinked metal rings, which are usually riveted shut on high quality pieces. It is available to characters from Ultima I through Ultima IX.

Description
A full set of standard Britannian mail generally consists of a coif, a mail shirt (termed a haubereon in comparable  Terran ages) and mail leggings (chausses). At times, mail gauntlets (mitons), mail boots and mail arm extensions for the haubereon would also figure into the ensemble.

Throughout the Age of Darkness and into the early Age of Enlightenment, chainmail armour was presumably always sold as a set. As time progressed (and as the Ultima game engine grew more complex and better able to support differing armour slots), mail became a commodity sold by the piece, and it could take some shopping around on the part of an enterprising adventurer to assemble a full outfit. In terms of blanket protection, the woven mesh of good mail is almost always preferable to boiled leather or padded canvas in terms of keeping its bearer from bodily harm, although there is an understandable trade-off with regards to expense and weight. While not as sure a defense as full plate, the comparative lightness and flexibility of mail often makes it the wiser choice in situations where encumbrance is of issue.

Trivia

 * The term "chainmail" is actually on neologism - at least as far as Earth is concerned. In the real world history of the armour it was only called by this name in eras later than the 1700s.
