The Kinetic damage caused to the flesh beneath the armor, impacted by whatever attack, is directly proportional to the oz (ounce) of the armor. Or, in simpler terms, the thickness of it. I.e. 3 oz leather would do very little while 10 - 15 oz would allow dispersal of force across the entire surface without causing damage to the flesh (rigidity is the important part here, as the harder materials are to prevent penetrating damage). (Source: Worn and fought in light leather, hide, chainmail, full plate, and brigandine armor).
[member="sabrina"] So if your armor, in your mind, is limp and light, then yeah, it basically wouldn't diminish the kinetic force of an attack.
