Sort of? I mean the battle armour we used to wear was bulky as fuck (though we wore other stuff depending on operations and the necessities of the field... LRR for example). It was contoured enough to provide mobility, but insulated enough that you don't basically allow total insulation of power over a small area. Skin tight armour is retarded and about the only time it would be useful is against persistent friction ala a motorcycle jacket and using a high tensile strength material like corduro nylon or leather (because you fon't want that armour riding up your back or legs while facing consistent abrasive resistance). Even then you have kevlar inserts. I have 16 in. shoulder width... but even with my fitted Dririder kit I look 18+ in. wide.Zhukov said:Ohhh, ohhhh, ohhhhhh, I smell someone talking directly out of their arse and being hilariously wrong about one of my pet subjects! Let me get in on this pile-on!Strazdas said:The purpose of armor is to take the kinetic impact of a weapon blow and/or bullet and distribute it as evenly as possible across your body so instead of piercing you it would simply give you a push. Therefore the most effective and thus "plausible" armor is one that fits your physionomy the best. As in, skintight armor would be ideally effective. Thus the "Breasted breastplate" is actually practical armor. Now there is other concerns with it, such as when it comes to swordplay a way to slide the enemy blow away is often more useful than a way to distribute the force, hence the corner-less design being popular. Theres also the fact that in medieval times it was much simpler, and thus cheaper, just to create a plank-style armor despite it not being the best possible one. Most soldiers could not afford armor, let alone good armor.
To be fair, you're actually not entirely wrong about the force distribution thing. Having a plate of metal (or ceramic in some modern armour) between you and a sharp thing turns a cut or penetrating stab into blunt force. That blunt force will still be transmitted to your body though. A layer of robust non-rigid padding (think of punching a mattress) will harmlessly distribute blunt force, but will be vulnerable to being cut or penetrated by sharp weapons. Hence why armour of old often incorporated both, with plates or chainmail on top of a padded gambeson or equivalent (also because metal on skin would be supremely uncomfortable).
However, saying that skintight armour would be "ideally effective" is complete bullshit and doesn't logically follow on from your previous point. See, another aspect of properly designed armour is deflection. For example, a good breastplate will stick out in a crease running from neck to waist. Thus incoming blows strike at an angle and some of the force is redirected out to the sides rather than straight into the wearer's chest. It's not skintight because being skintight in shape would not have that effect. Natural and unavoidable weak spots are those parts of the body which create natural "valleys" such as the armpits and where neck meets shoulder.
A "breasted breastplate" is just about the worst possible shape for a breastplate. You're creating unnecessary weak points all around the boobs and a massive one right in the middle of the cleavage, right over the fucking heart. Worse still, the shape will guide any blows that land nearby straight into that weak spot. It's a big, stupid invitation to get stabbed directly in a vital organ that will even collect extra blows that weren't going to land there.
Still wear less armour than all you grid iron pussies. Git gud.
Even then an accident at high speed bitumen or cement roads will eat straight through it after about 1.8 seconds... and hopefully you don't just *stop* even if it does. It's not bouncing or sliding that will kill you, it's the sudden stop.
So no... there's fuck all excuse for skin tight armour. The only real condition is mobility and weight. You see this with even modern armour technologies. Putting as much insulation between you and the bullet or the environment is beneficial. For example, looking at construction safety helmets (where things are designed to protevt against heavy things falling on your head) there is an internal 'cushion' like effect to help insulate the blow. The helmet should fit well, but you shouldn't feel the crown of your head hard against the shell of the helmet.
There is a reason why peasant armies had clubs and maces... beating them against the helmets of armoured people. This is principally why helmets often had a weird conical-esque shape to help divert the blow away from transferring all those newtons into your skull. Sure it will bash off your helmet and give you a concussion, but better that than dead.
Ditto motorcycle helmets have a insulative polystyrene foam inlay that is designed to crush up, and break apart.
If you didn't have it the force of your head hitting the ground would transfer directly through the helmet with little to no increase in energy diffusion into the fibreglass shell. In a bad motorcycle accident the fibreglass shell had utterly shattered and splintered, and the foam was near disintegrated and blown apart ... I had massive head trauma, but without all of that pulverizing, insulating material my skull would have likely fared no better. If my head was hard up against the fibreglass they may have beeded a bucket rather than a brace and bed. Motorcycle helmets are bulky for a reason.
Oddly enough D&D ... the game that gave us the hilariously bad chain mail bikini... has the best idea of armour. Wear as much as possible as you can carry and won't hurt your dex, wear as much that you can still move about as quick as the dwarf, wear as much but won't drown trying to cross a placid fjord on foot.
