Note that the weights listed for most large suits of armor such as hauberks, plate, and power armor, are figured for their “distributed” weight. This assumes the armor is properly fitted, which takes a Knowledge (Armorsmithing) roll, some basic tools, and 1d6 hours. If armor is not properly fitted (such as when wearing armor taken from a foe), the weight is typically doubled.
