So we all know wearing armours without anything to protect you against abrasion is not very smart because if you ever go down at speed: 1. Whatever pants you were wearing over or under the knee armours will disintegrate in a split-second along with the straps holding the armours in place. 2. Off goes the armours with nothing holding them in place, then it's your skin, soft tissues and finally bones. But what if you had kevlars underneath the armours? Something like the Draggin K-legs maybe? Would the armours have done their job absorbing most of the initial impact by then? I'm not curious enough to actually test this out myself, so this is all hypothetical.
