We are unable today to differentiate mail for tournament from mail for the field, but
clearly the privy wardrobe saw a distinction.
And specific tournament armor isn't limited to mail in the 14th century.

Of course there are special tournament swords, coronels for the lances, and horse armor specifically for tournament as well. Many of these seem to be lighter in weight (leather rather than iron) or covered with expensive materials to increase their bling factor in the spectacle. A number of them seem to be worn out.
There was a noted difference in mail for the tournament vs. normal mail. At least one set of mail for tournament is without rivets. perhaps the rings were overlapped and flattened, but the steps of drifting and riveting were deemed superfluous. That's not quite what we perceive as "butted", but it's not riveted. That leaves us with a mail shirt which looks the same from 10' away, but isn't as strong, so more prone to "wearing out". The older school of thought is that tournament armor was stronger in some way, in which case the no-rivet mail would have to be all welded rings or half punched and half welded. But would such an armour be the first to the junk heap?
