In Dragonslayers RPG, the benefits of nonmagical armor are cosmetic unless you have the Armored (2 SP) feat. Whether they notice it or not, the heroes seem to get by just fine without wearing armor.

Most suits of armor are made of steel and come in one of the following varieties: mail, scale, plate. Other varieties are possible.

Plate armor doesn't offer superior protection (watch any fantasy film), but it is neither especially noisy nor especially cumbersome.
