I've been thinking about this for a few days. What if I had a Kevlar gambeson?
Is it feasible? Could the linen/cotton/wool bits be replaced with Kevlar or some other modern material? Has anyone done this before?

The DOD has had them since the 80's, and I just spent the better part of a year wearing one in Afghanistan :lol: . But seriously, a modern military flack vest is just a kevlar gambeson, even if the style is different. What I find interesting is that they started adding plate reinforcement in the late 90's and now some combat troops are wearing plate carriers and dispensing with the kevlar protection. The modern path of armor development is similar to the middle ages, just with different materials.

What an interesting point about the transition from kevlar to plate!
then there is also "Dragon Armour" in the works... anyone ever see that before? http://en.wikipedia.org/wiki/Dragon_Skin_(body_armor)... nothing really new... well probably be wearing full plate armour in another few years again like this http://en.wikipedia.org/wiki/Powered_exoskeleton
Fencing jackets can also be made from kevlar.
I wonder where to buy a fine weave kevlar, since I'm only familiar with the coarse weave as used in shipbuilding. A kevlar brigandine with kevlar-epoxy plates inside seems like a nice idea. Similar to dragon skin actually...

Do note that though Kevlar does protect against bullets up to a point (high velocity bullets from large caliber rifles still penetrate Kevlar without plate protection) they don't protect against stabbing weapons (like knives) any better than other cloth materials.
Isn't Kevlar hot, sweaty and uncomfortable to wear or is that just a myth?
Natural fibers can be very comfortable to wear.

I don't know how much sweatier kevlar is than natural fibers, but kevlar vests might be sweaty because they have 10 layers or so

I think that there are some stab resistant Kevlar varieties that are used by corrections officers. Those most likely work better than natural fibers.
It would be interesting to make a gambeson with alternating layers of the bullet and stab resistant fabrics. That might either work great, or be lacking in both areas, and really suck.

I wore a kevlar vest with plate inserts in the back and front in Timor. The primary identified threats were from machetes and hand propelled ballistics, not too dissimilar from what soldiers faced historically.
What about d3o?
Has anyone ever put it inside his gear? Like between authentic fabric ?
I think it would make most wonderful gear for steel fighting with no modern material that can be seen by others.
Heres to people who dont know what d3o is:

Combined with kevlar + armour plate it would take care of blunt trauma really well but I don't know or think it has bullet stopping qualities or cut protection on It's own.
Seems like a soft and spongy material that reacts to sudden impact by becoming very rigid and by spreading the energy over a wide area. I wonder how thick or thin it can be and be effective ?

Stabbing can mean two things: the blade pushes the fibres apart, or it breaks them. The second is much less likely with aramid fibres than, say, wool. The first one is simply a matter of how tight the weave is.

Really? I'd love to hear some stories and/or see pictures sometime... I knew that Indonesian pirates still used swords occasionally, at least, they did some years ago. What kind of hand propelled ballistics do you mean?

I've read up on the "Dragonskin" armor and I would not trust it. From their own test reports, the weight is more than 50% greater than for the kevlar and plates we wear now, and the price is about triple for the same amount of protection. The only advantage seems to be flexibility, and even that is questionable. From reading their own reports, they required add onplates despite the "scales", which would drive the weight to around double what we wear now. The scales seem to be a marketing gimmick without much practical use.
They tried to create public pressure for adoption by the DOD with a media campaign a few years back, but fortunately it didn't work.
Dragon skin is a joke, it just plain doesn't work anywhere near well enough to justify the increased weight. Its performed poorly in every controlled scientific test done on it.
Having worn Kevlar nearly every day for twenty years, I can say this sounds like an excellent way to get heat stroke. A Kevlar gambeson under armor? No way.
One of the things I found interesting during my time in the military was the evolution of the armour.
In 1992 I was deployed to Somalia with a Kevlar Helmet and Flak Jacket. The helmet had a leather and webbing suspension system that, while functional, was almost guaranteed to give you a head ache and the Flak Jacket was generally agreed to be useful for keeping you warm and safe from rocks (those Somali kids were wicked with their slings) but not much good for direct fire.
Fast forward to 2006 and my issue for Afghanistan was a much improved ACH (Army Combat Helmet) and IBA (Interceptor Body Armour). The ACH had a gel pad suspension system and allowed you to do such amazing things look up. The IBA started off as a Flak Jacket with two ceramic SAPI (Small Arms Protective Insert) plates but throughout my tour more armour was constantly added. First the kevlar gorget, then the kevlar groin protector, then side SAPI plates, and finally kevlar pauldrons. The added protection was welcome while I was in an Uparmored Humvee (even if the added bulk made it nearly impossible to turn around) but dismounted patrols sucked. The added weight and bulk in the temperatures we were working in made me think of the knights during the First Crusade. The biggest problem (aside from the over all bulk) that I had with the armour was that most of the weight was carried on the shoulders. The kit I'm putting together from Allan @ the Mercenary's Tailor has much better weight distribution.

I have worn Kevlar for maybe 8 years +/- now on motorcycle rides/rallies ...the sweatshirts & gloves come from a company in Australia http://www.dragginjeans.net/product/k-shirt the sweatshirts run a size small to the US.. They are pretty dang comfortable but not for keeping you warm as the wind goes right through them...I once had a video posted up that I did back in 2005 with me slash cutting my arm a few times with a Japanese kitchen knife, the gloves I use when cleaning the sharps..awesome stuff !

Hi Paul, the main ballistics used were darts and slings like those described in this link;
http://aviationweek.typepad.com/ares/2007/04/why_wear_body_a.html
They seem funny until you see what they do to something they hit. Also, while I was there more than one digger was saved by his body armour from a machete or shiv, but man it was hot and hard to run very far in.

Interesting article... :eek: Not funny at all...

Sorry, I meant the darts themselves seem funny, usually having ribbons etc attached, but yeah, they are lethal.
