It is a lot easier to suggest things to read than to try to answer your specific questions for free. If they can tailor the mail right, it should not be a big deal over the clothes underneath. I don't know how thick the kevlar padding you are thinking of is though ... generally thinner, like 3-6 mm, works better, but some of the "to the pain!" fighters layer on more. If you want a helmet 6.6 mm thick in front, you might try an armet with wrapper. I can't really comment on the feasability of types of armour which never existed, like the rifle-proof visor you are talking about, though. They don't have to know what the visor is proofed against. Fiore has a few lessons like that: "stab him in the visor, then if that does not work try flipping it open! Get him in a lock and give him a few thrusts in the back to see if his armour is weak there, and if that does not work try something else." I don't know what I would make a 21st century person roll to guess where low-tech armour is weaker.

Re: [Cutting-Edge Armor Design] Real World SCA-legal Armour and Ballistics Armour
Thinking about PC reactions to all this, taking a few rocket-propelled grenades along seems like a good idea, in case they get in a fight with vehicle-mounted enemies. And after seeing Vargas in action, the temptation to use one on him would be strong.

We did get permission to carry weapons for protection, because we're legitimately at risk of being the targets of a kidnapping attempt. But somehow, no one felt rocket-propelled grenades were vital equipment for emergency self-defence. The weapons for self-defence were acquired from a black market contact in Mexico. One PC did try to buy grenades, but when she heard the $500 asking price, she backed out. We weren't supplied with an infinite supply of black funds, after all. We bought 9x19mm pistols and a couple of AR-15 type rifles, as well as an AK-type.

I suspect that a fully enclosed helmet and neckguard as thick as you are talking about in front would be the kind of thing which got worn a couple of times then relegated to the storeroom, because it caused too much neck pain and limited breathing and vision and made it hard to shout orders, but if this guy is worried about preternaturally skilled assassins and too macho to care about comfort than who can say. He is supernaturally strong, and there is some crazy thick armour for jousters or engineers in the front trenches (but like I said, it is not that thick all over). So maybe you could make a grand bascinet, or an armet with wrapper, have the properties you are looking for. There was a famous paper where they had some interpreters at the Royal Armouries run on a treadmill in 15th century armour with one of those apparati for measuring oxygen consumption on their faces. They did not have the visor down though. Armoured fighting burns a lot of oxygen, but so does diving. So I am more comfortable suggest things that might work than saying "yes or no."

You could try selling it to him as an oxygen enrichment system. That should give Vargas a few extra FP. See Bio-Tech, p44.

Re: [Cutting-Edge Armor Design] Real World SCA-legal Armour and Ballistics Armour
For full coverage, 125 lb is an areal density of 5-6 lb/sf or 25-30 kg/m^2, depending on the size of the person. Checking around, you can find level III armor in that mass range and level IV that's slightly above (I found multiple claims of 25.9 kg/m2 and 32.5 kg/m2 for level III/IV, which are probably all reselling the same thing), but it's not metal (that system is ceramic wrapped in plastic and fiberglass); best figures I can find for steel plates is about 10 lb/sf for level III armor, so anything you can do in full coverage for 125 lb steel can be made swiss cheese by an assault rifle, though variable thickness is obviously an option (the simplest option is to not use the plate for ballistic protection -- just have ordinary weight plate, and put conventional ceramic composites under it).

I did initially consider ceramic inserts for the chest area, but given the good performance of advanced alloys, ultimately decided that it wasn't necessary. I've found 10 lb/sf Level IV flash bainite steel for vehicles, but I'll be assuming somewhat inferior performance for any kind of alloy that is practical for working into complex shapes. Given that the ballistic polymer underlayer will be around DR 9/4, I expect it to perform very well against spalling. Some of the experiments I found also suggested that even if rifle rounds penetrated steel plates that were not quite thick enough to stop them, they might not always penetrate a layer of ballistic fabric underneath. By GURPS DR rating, it's seems fairly practical to get armour that will mostly stop carbine fire, even on the limbs, and will stop almost any kind of rifle fire on the chest and skull. It's true that two layers of armour that individually are not rated to stop a round will not combine the way GURPS rules make them do, but almost Level III armour seems like it ought to stop or at least significantly reduce the lethality of 5.56x45mm from many of the short-barrelled carbines popular today.

Sounds like a good idea.

Re: [Cutting-Edge Armor Design] Real World SCA-legal Armour and Ballistics Armour
If you're looking at http://www.flashbainite.com/cm/dpl/i..._Challenge.jpg, that's not level IV. Level IV is 7.62M2 AP at 868m/s (2848 fps), that graphic is at 2100 fps. Pretty nice deceptive advertisement, though.
