This is not a discussion on if it existed. It did. To the degree it was used can be debated, but it has happened.
This is one on how to make it work in fiction, and since its going to be a thing despite how many of us wannabe historians and actual historians might cring, its still going to be a thing in fiction for decades to come. So how to make it believable, if not realistic; after all, its fiction. You know the writers are lying to your face, its a work of fiction. You just have to add a few truths here and there to stave off the the part of the mind that goes: Hold on a minute! So get your ideas on the table and lets see what we come up with.
My take: There are a few things we need to solve, to make this work-ish.
First problem to solve is production: What is it made of. LEather, of course, but what animals. The problem here will be quantity and quality of leather as most animals won't make for good armor, while others might. Regardless, this is alot of time and energy needed and a grand investment as you have to raise the animal to the point it can go to market, or track it down and hunt it. If its below a certain age, probably not going to be the best quality you can get for your armor.
Here are some examples.
Cattle: Usually an adult domestic cow of some sort, this is one of the more common ones out there and is noted for being very strong and durable. Due to these qualities it gets a lot of mileage out of what can be made out of it. Those made from the younger calffs are usually for more high end designer bags due to being finer but not stronger than an adult cow. Both can be used for the shell (outer) component of handbags and clothing. I think most saddles are made of this as well.
Buffalo is tougher, perfect for a good pair of workman gloves.
Goat: Probably not going to be used for defence. While great for clothing and bags, its pretty thin.
Lamb: Softest and most elastic. Often form fitting, comfortable against skin, and can be reshaped after wearing. Good for clothing and gear, maybe not armor.
Deer: Soft and strong, flexible, washable, reslitiant, perfect for high use items like boots, gloves, and so on. Probably not the best for taking up arrows. Elf, is heavier and thicker, but I doubt it could muster much defence. Mose has been used by some First Nation Peoples when they were dealing with other pregun foes, so it might work.
Pigskin: What American Footballs used to be made of. Soft, thin, durable, and tough; most commonly found in suad now a days. Not sure if wild boar is any different but doubt it.
Crocodile/Alligator: Depends on what area you get it off of. The belly and inner leg areas are most often used in clothing and accessories as they are softer and more flexible, but give crocodile time to age and you can have tough back scales. There are even rumors of crocks that have survived bullets, like Africa's infamous Gustav, but most of them probably can't take the lead. Maybe arrows or bolts froma distance, but not sure. Either way, the harder back scales is probably what you want.
Kangaroo: Perks of working in the arts and crafts area of a Boy Scout summer camp. We did the leatherwork merit badge. Anyways, its from here I learned Kangaroo is often used as shin guards for football/soccer. Having taken hits from there from a soccer ball, that has to be a good guard.
Stingray: More durable by a long shot than cow hide, it was used for the handles of Katanas back in the day. Now mostly bags, wallets, and belts and the like.
Second issiue, in what form. I think there are a few we can pick from .
a.) A coat made of scales that can be replaced as the get damaged. I learned of this one from National Geographic's: Tut's Treasures-Hidden Secrets. They were tightly laced together, almost giving it a dragonhide look.
b. Some bracers and shin guards, say for archers.
3. A combination of it with metal, being used in areas to have some protection but still allowing the rest of the armor to have maneuverability. After all if you can't move fast enough than your foe can find a spot to stab you, you won't last long. Shin guards, keep that from getting damaged. Arm guards, well, a bow string going against your arm hurts alot...alot alot....alot alot alot alot.
Final issue, who would wear it. I can see town guards, maybe some higher ups in villages using it. More hunter gathers might have something similar. Most would probably be more mercinarial types that couldn't afford metal armor yet, or used in the combination fashion. Gambeson, padded or quilted armor, works pretty well, and can be used by most of the lower ranking troops. Maybe lower ranking commanders or soldiers that have proved themselves so are given something to add a little more protection might be in order.
That's all I can think of. What about the rest of you?
