These are the suits of armor available to the party or the ones they have discovered and know the stats on.
Any of them being held by the party will be noted.

Armor in general comes in three types and all protect from damage to a degree. Light provides the least protection but its better than nothing and it does not impede any other skills like stealth or movement Medium provides more protection, but impedes the movement of the user. Heavy offers maximum protection, but greatly impedes the movement and agility of the wearer. However if you can take that many hits dodging is not as bog of a concern.

There is another class, but it offers no protection. Its clothing. If course clothing is useful to protect from the elements or allow you to fit in the local area or match a local faction.
